In my experience, most people who struggle with WFH lack specific material things like space, a quiet home, a schedule anchored by the presence of loved ones who live nearby and a functioning community which they're a part of, good mental and physical health, coworkers who will help them without a fuss, and a million other things.

I think people who take the structure of their lives for granted say things like "problem is most people aren't disciplined:)", but this definition of discipline is directly related to how nice one's house and home life are. This pull-yourself-up-by-the-bootstraps mentality of "disincline" and "work ethic" lets you feel smug about the fact that you're doing better working from your nice home office as an L5 than your new intern who's working from the kitchen table in his family home next to three other people.
