Legislating what humans are allowed to want and need and then calling that "post scarcity" has led to immense suffering over the past century. It continues to be a temptation of authoritarians who want a utopian society and want it now.

Perhaps you meant something else? Do you think if we just had more intelligent robots to do our work for us we wouldn't need to work anymore? I think it's impossible to do it with existing technology, although I wouldn't rule out future technology. This is where basic income enters the discussion as a bridge from scarcity to post-scarcity.

As an addendum, I believe we are approaching post-scarcity for a higher and higher percent of the population who are perfectly happy with what they have (this includes early retirement, financial independence, long sabbaticals, etc.). We are also approaching post-scarcity in some industries, such as software where the majority of it is "free", although of course "free" means different things to different people which is another discussion.
