Personally, I wouldn't even call acquiring points simple. Right now when I fly it's complicated enough to pick a flight. But one of the points of a frequent flyer program from an airline's perspective is to encourage me to fly their airline more often. So if I belonged to one of the programs, I'd also have to be doing the calculation of, "Oh, if I fly X instead of Y, I'd get enough miles to level up in status and/or get a free goodie." Which means having to learn and keep up with the rules, balances, and rewards of the various programs.
Do not want.
