>We just don't know and can't really imagine what it's like to live in a world where you are entitled to money for existing, no strings attached, pretty much from cradle to grave.

Sure we can. As I noted, wealthy people live in this world already. And we don't see all of them turning into couch potatoes once they have passive income equal to UBI. Sure, there's a human tendency to enjoy leisure. But there's also a human tendency to enjoy work. And a human tendency to project negative attributes onto others we don't know. ;-)
