If you promise everyone money for life, many people won't bother to create wealth. Wealth creation tends to involve rocking the boat. Have you heard of Duke Nukem Forever? They had scads of money and spent years trying to make the next perfect thing and failing to release because it wasn't yet perfect. Then they would start over because they were taking so long that technology had changed and all their work was out of date. I think they finally released when they ran out of money.

A lot of people will do absolutely nothing if they have money for life. People are neurotic, perfectionistic and on and on. We do an awful lot of stuff we don't really want to do because we need the money. We don't want to starve. If we guaranteed a minimum level of comfort, a great many people will do absolutely not a thing because doing stuff is scary and hard and what if we look like fools? and on an on.

How many important things are there? Lets go with 10,000, which I think is _extremely_ generous. Perhaps there is a better way of enabling people such that we find those 10,000 people. UBI doesn't need to be the solution.
