But what's stopping you from just working hard, saving your money, and then taking extended time off of work to do what you want to? Why does that money need to come from other people? Maybe if the government just let you keep the majority of your earnings you could use that money to "work on what (you) like or not work at all when (you) don't want to".
Actually, nothing's stopping me from doing all of that. I'm also not asking for BI (it sounds like a bad idea long term), I'd take it if it was offered though.
Personally, I'd love to get BI. That would free me to work only on what I like, or not work at all when I don't want to.
