I think there's a huge difference between everyone having unlimited material goods Star Trek style and UBI being a floor for everyone. I think of UBI as a floor that I can go below no matter how bad I screw up. If I start a company and max out my credit cards to fund it and it goes belly up then no matter how much I still owe to Chase I will still get my $1000/month to pay the rent and put food in my belly.

But I will still want luxury goods and I'm willing to work for them most of the time. I want a phone upgrade every few years which might be a luxury I couldn't afford under UBI. I like flying airplanes and certainly would need to work to pay for that hobby. But if I get burnt out and want to read books for a year then I could do that too!
