There will never be post-scarcity, because we'll never have enough. Using cutting-edge technology always requires people to work hard to build said technology. If it didn't require work and just wishful thinking we'd already have it. The builders and engineers will always want _something_ in exchange or they won't make said tech accessible to you. The curiosity of nerds only gets you so far (see open source UX).

Maybe you won't have to work/pay for food if accounting for it becomes more work than producing it (if sufficiently automated and not resource-constrained). But if you want to live in a hip neighborhood (by definition there is limited availability), have your own flying car, go on vacation on the moon once a year where real people service you etc. you'll have to work for that. Because the ingenuity and work necessary to make this all happen will still be enormous.

Maybe you think you'd be happy with your today's lifestyle, which might be attainable for ~free. But I think the reality for most is that they'd grow jealous of their friends posting selfies from the moon and resent "the evil rich" again.

The small amount of work necessary to _survive_ today would sound marvelous to someone from even 100 years ago (clothes, food, shelter outside major cities). Mowing one lawn for 1-2h every day would probably be enough for that. But surviving isn't the point of being human, it's about stretching the limits of what is possible and that will always take as much work as we are willing to put into it.
