I don't think there is any sort of unanimity regarding UBI. Being compensated for staying home is not UBI, because it is not ongoing.
I'm against UBI for reasons that became apparent while playing MMORPGs. Stay with me here and I'll explain.
Players of an RPG want a fun game. But they also want to succeed/win. These goals partially conflict. If they prioritize winning too highly, and pester customer support to make the game easier (nerf), the game loses it's fun. Even (in my estimation) to the people who pestered customer support. Because some people aren't self aware enough (kids) to realize that the challenge is what makes it fun.
In life, we want to be lazy. I certainly do. And that desire makes me think a UBI would be quite nice. But I also realize that I most certainly would be lazy. I'm already working less than 20 hours per week (pre-COVID) because my mortgage is paid and I don't really need the money anymore. With a UBI I might stop work completely. But as a society, if a lot of people like me slack off more, the real economy will suffer. Less hours will be worked, prices will go up, and the economy will be more depressed and sluggish.
Robots could save us but we are not there yet, not by a long shot. Maybe we are there in very specific manufacturing industries, but no robot is going to install a new roof on my house (for example).
So I think we should wait until after all the jobs are taken by robots (rather than thinking it's imminent when it's most certainly not) to institute UBI. Eventually. But not any time soon.
OTOH I'm perfectly okay with a means-tested payout to people who really need it.
