The thing that I am preaching here is that people are different, so… maybe there actually are many people like that.
There is a general ethical problem in our society: do high IQ, high human capital people with impulse control have a responsibility to model behavior that will also work for those without the positive traits? Or should the lucky upper echelon feel okay to conduct behaviors that are safe for them but risky for the lower groups?
Examples: recreational drug use, single parenting, pursuing a career in the arts, dropping out of school, polyamory, etc
UBI-dependent lifestyles will likely fall into a similar pattern. Some people will thrive; some will be destroyed by UBI. But it’s hard to legislate that some people should get UBI and others not (for their own safety/benefit).
It’s a bit of an orthogonal point, but I wrote Urgent Coordination Problems Require Narrow Mandates in response to Eliezer’s original post.
tl;dr : if you want people to accept some kind of universal mechanism to solve a coordination problem (e.g. AI development treaty), you’d better be very careful to ensure that the proposed agency has an extremely narrow mandate.
