at least you don’t become deadweight in the economy
In theory, yes.
Reality: we already have shit welfare programs and I doubt UBI will fix it. I also doubt we'll even get to a point of UBI in my remaining career time. At least not without a lot of blood.
The present as is is pretty bad, I'd hope we can fix that before theorycrafting the future. economists 100 years prior theorycrafted 15 hour work weeks, and look how far we've come.
