I don’t understand how UBI forces you to stop working at your job. Wouldn’t you potentially be paid even more if everyone who does that job but hates it stops? And the compensation to do it increases to compensate?
Vain and selfish people probably aren’t going to sit around and live on the basic level. It’s more about providing for the ignored, the sick, and enabling people to take risks in the market without putting their family’s lives at stake.
