I agree and disagree. I'm certainly not arguing that industrialization isn't miraculous. Even from a parenting perspective, I think most would rather raise their kids in a stressful nuclear family than watch half of them die from preventable diseases. If you read about the anthropology of childrearing it's filled with endless heartbreaking accounts of parents having to make choices about letting one kid die to focus their resources on more viable children.
But the point I do want to make is that our physiology and psychology is largely fine tuned by evolution for a certain operating environment. When we step outside that environment, it often introduces dysfunction in unpredictable ways.
An extreme example: as land animals we wouldn't survive very long at the bottom of the sea. More prosaic example: it's undeniable an environment with many more and tastier calories creates chronic health problems. Metabolic disease is virtually unknown in hunter-gatherers.
A rough heuristic is that removing purely adversarial elements from the evolutionary environment produces an improvements. Pathogens, predators, physical injuries, birth-related traumas, and famine. Removing or mitigating those elements are the main reason life expectancies have improved relative to hunter-gathers. But once you step outside the totally hostile elements, most environmental changes tend to be neutral at best and harmful at worst. Physiology and psychology rely on delicately tuned equilibria, which are easy to disrupt. The consequences aren't terrible, but do tend to subtly accumulate over time. Hunter-gathers die fast because they get a concussion and bleed out. Westerners die slow from the accumulation of plaque in their arteries.

Agreed. My point is just that we should look at physiology and psychology as guides, not anthropology (which is interesting but not necessarily prescriptive).
A diet of Twinkies and Coke is obviously terrible. But a finely tuned, balanced modern diet guided by nutritional science is likely superior to a primitive hunter-gatherer diet. There are plenty of people today who are in great physical condition; this is very feasible within our modern society.
Similarly, different modern countries often have differing familial arrangements, so we can look at empirical outcomes there instead of trying to guess at what our distant ancestors did, who had little choice but to do what they did, not having modern civilization as an option.
Longer on average, yes, but I highly doubt healthier. I think we'd be in awe of the average health/fitness of a 30 year old hunter gatherer from 100,000 years ago, compared with the average corresponding human in modern times.

They're different, not really better.
Hunter gatherers definitely got more involuntary exercise. But modern people can choose to get better (more specialized/effective) and safer exercise than ancient people ever could have.
Hunter gatherers had to eat what was around them, and would involuntarily periodically fast. It's much easier and cheaper for modern people to have a varied diet. Many modern people also periodically fast. But you have to choose to do so.
Ancient people typically struggled with parasites and various diseases. That is largely not a factor in modern life. Modern people sometimes are affected by serious pollution issues - modern air quality from burning fossil fuels may be such a crisis. Airborne lead from leaded gasoline was almost certainly one. It's difficult to compare the effects of such problems.
There's also a pretty strong selection effect going on here: lots of people 100,000 years ago used to die. People would die in childhood, people would die in adulthood. This mean that women had to have lots of babies, which means women died in childbirth a lot.
So, I think it's true that, left to their own devices, modern people tend to be somewhat unhealthy. Mostly due to laziness. But modern people also pretty clearly have the opportunity to be much more healthy than ancient people.
Most likely we would not. There are whole classes of sicknesses that dissappeared last 200 years which were caused by lack of various nutricients. Both difficulty to get them and lack of knowledge played role.
Add to it easy to cure sicknesses, injuries that are nothing more and would kill you back then, their higher chance to contact said injuries and it is unlikely they would be so much healthier.
Also, there is reason why agrarian societies pushed away hunter gatherers - it is just easier to stay alive and healthy. Getting all the food a hunter gatherer in all seasons is hard.
In addition, childbirth in their society would both kill or forever damaged more women. They would also have harder time to leave physicly abusive situation, meaning likely more of it, meaning yet another negative impact on their health.

No.
Agriculture exists because it supports more people per unit of land than what the traditional way of life did (on average). This is as hard of a fact about history as you're going to get.
Now, you need to be savvy about what the statement is not saying. It is not providing a reason for an individual, or group of people, to make the switch from hunter-gather to agriculture. History did not lay that choice upon the discretion of people. It plays out in a much more complicated way.
Since the relatively natural land will only support so-many humans per acre, what happens when there are too many children? They move. Okay, what happens when that next region has too many children? Do they start making farms based on their ledgers of expected food production to population ratio - NO. The people who have political decision power are not the same people who starve or get their heads lobbed off as a result of their decision. If anything, a leader would prefer the neighboring tribe lose a few heads to adjust for the starvation problem. Do people start "switching" to farms anywhere in this? No. Only over a vast period of time, many climates, lots of movement, tribal reorganization, do people start... semi-nomadic animal husbandry. One day this will lead to agriculture.
All of this is vastly more complicated than it is on the surface, and the newly-established farmer occupation, when it comes around, could possibly be seen as the sucker at the table. There was constant tensions between "civilized" societies and their tribal neighbors, and only over the super long term does the higher calorie density of civilization win out. Even if their soldiers are shorter and stupider, there are more of them. We don't read about this, because recorded history picks up at a time when superior organizational capabilities of civilization is starting to give them a quality advantage as well (and as a side-effect, writing).
You did not done much reading about history and military?
Anyway, easier way to get food and not get hungry or starwe is strong reason to switch lifestyle. Human societies of all kinds have been doing exact that decision over and over.
