>But the people "on UBI" will be everyone.

This is exactly what I'm trying to point out is the issue, if everyone had parents who gave them handouts we should expect the trend to be towards our stereotypical view of a deadbeat who lives at their parents house. All these people who you are talking about had the privilege of having a healthy combination of both the carrot and the stick, and while you are completely right they could provide value if they had UBI now if they instead lived in UBI for generations their priorities could have been completely different. If we imbalance this important piece of society too much we will be running a modern day behavioral sink experiment on the population.
