Maybe in the distant future we do not need people to work. But we are currently dealing with the largest retiree population our country has ever had, and more money chasing after fewer goods and services nearly crippled our economy with stagflation. It takes two weeks to get a plumber right now in our area.

If you also hope to implement UBI nationwide, you need some expectation that it pays for itself with productivity gains. Otherwise it will all get inflated away into nothing.
