How about you give them a wife and kids to take care of at the same time. Life would feel pretty pointless if I was only working to support myself

I don't know how you've managed it but you've managed to invent toxic-domestication, The idea that someone's life can't be worth living unless they are working. I don't know maybe you're young but when you get to your 40s you begin to realise that actually what you really want out of life is just to be left alone, you really aren't craving notoriety. If you can just sit in the hobby room and build airfix models or whatever then go to the pub, for the next 40 years you'd be happy.

I really don't know why you're arguing about this because there have been actual experiments where people have been given UBI and pretty much everyone ends up just going and doing their own stuff. I've never heard of anyone complaining about being given free money.

Everyone defines themselves by their role

I don't and I bet many people don't as well. I define myself by what I know, who I know, what I believe, like and dislike, have done and can do. Roles can be assigned, but they only serve as oversimplifications of what's expected of people. The role of "mother" only means that a woman has one or more children. Whether said children are blood related, adopted, whether she's a "good" or "bad" mother, whether she's married, widow, single, etc etc, is up in the air.

Your second argument there doesn't need roles to be answered either, or do you think only specific roles can help people? Life isn't an RPG with clear-cut classes

You're so right, how can I find meaning without making somebody else's money for them? Woe is me...
