Futurist nonsense
All businesses have a function, that's why they exist (unless artificially created or propped up by the government)
Tell me, where would this money to fund UBI come from?
It's a wonderful utopian ideal where people could just be free to hang out but it's just that, utopian
Not true. Things can happen in stages, including the development of society. Many businesses exist because of the desire of one, or a small group, to have the utopian life than you dismiss, but through the process of getting other people to do the work for them. I don't have the answers, I just think it is shortsighted (and more than a little eyebrow raising) to say "see, give these kids what they need to survive and they just go off and enjoy there lives, then there is no one left to clean up after me when I'm done eating the food someone else made for me! World collapsing!"
