By the time I was old enough to work, I had recorded dozens of my own songs and made countless websites for fun. I made computer graphics and learned tons about computers and could fix them for all my friends and family. These were all forms of "work", valuable to others (to varying degrees), and I received zero payment for any of that. People like to do things, particularly things that benefit those they care about. Not everyone is like that, but we don't actually really need everyone to be like that, IMO.

Aside from the strong selection bias, you've also been raised in a culture that both works and values work.

Now imagine you're a third generation UBI recipient. Your parents never worked, and you're surrounded by people who don't even "work" in the way which you describe it.

At that point, I have very little hope, even for people predisposed to it like you.

I'm not sure that's a guaranteed future. Even today we offer subsistence living with welfare and food stamps, and nobody ever brags about not working because they're on the dole. Even if UBI is better than the current welfare system, it's not likely to be enough to support a middle class lifestyle. People will still work because they want to get ahead in life.
