[parineum]

There will always be scarcity for goods whose value is derived from their scarcity.

Maybe food won't be scarce (we wre actually very close to that) and shelter may not be scarce but, even if you invent the replicator, there will still be things that are bespoke.

[exe34]

there are levels of post scarcity. if food, shelter, medicine and leisure are available to all for almost no toil, then we're in post-scarcity. You'll (probably) never have your own planet. You might never be able to convince a certain artist to produce something for you personally.
