It is important to note that we are talking about extremes now. Up until now, the rules mostly encouraged self-governance and, in general, well, not being an asshole. That has been slowly eroded and we are in an expected spot, where some will push things to its limit.

While it is easy to be annoyed with those people, I would like to posit that they serve an actual purpose in the society. In a very tangible sense, they tell you where the lines actually are.

I disagree - I think those people are, to put it bluntly “the reason we can’t have nice things”. The only reason those lines need to be clearly defined is so those people know how hard they can push. If it wasn’t for that we could share.
