Even if you’re competent and useful, work is an incredible sacrifice. Perhaps only 10% of workers (the most unattached and lacking in obligations) would voluntarily work. For example for parents there are only a litany of bad choices available. If UBI is offered, why would most people suffer through their work sacrifices.

That's not even close to true. Basically every study on UBI, everywhere, has shown that either more people work, or employment stays about the same, but in each case happiness and health go up vs the control.
Since it's very clear you haven't researched your claim whatsoever - why are you making it? Why would you say something so wrong with so much confidence?
Because UBI and negative income tax doesn't provide the same lifestyle as working. It's a floor, no-one is proposing UBI at middle class salaries.
