Well... That leads me to a dark line of thinking... Jobs that are actually worth something are constrained by resorces we have and could extract if we're going by a "what is nessisary" line of thinking and who can just be cut out of the economy, we can't magic them out of thin air, it's part of the reason why it's so popular, also UBI would never work without keeping it low and having it replace existing welfare structures and aggressive taxation of the 1% and 0.1% (something I am for but that's tough when your population is comprised of mostly economic laymen who Don't Wanna be tAXd. )
