There have been periods of human history within some groups that did have no needs scarcity. Shelter, food, water, all there. Replenishing faster than they could consume it.
Star Trek addresses needs scarcity to a large degree, instead of want scarcity. Of course, the TNG makes it a little more clear that they can make anything you want, which who knows if we get there.
A good example would be do you have somewhere to live? Need Scarcity met. Do you want a high floor overlooking the Nebula? Want Scarcity, not always possible.
Of course it could be argued that if you could go multiple times the speed of light in a infinite universe you are likely to find something that you want.
People will desire these non-fungible things.
This is the case where if I were to replicate it, what would be the difference? Do you think if we got to that point we could intellectualize that the same molecules are the same molecules or not?
