Removing scarcity is pretty fricking hard. Obviously you started with energy, because it’s so universally useful. But clearly that’s not enough, because you recognize that matter replication and space colonization come next.

But let’s say you’ve got a replicator. It can make anything you can think up… and you’ve got a scarcity of good ideas. Let’s imagine someone else has a REALLY great idea for a replication recipe. Why should they share it? What can you offer them to convince them to share it, assuming they won’t out of good will? All their material needs are met, so where’s your inducement? Trade your own good ideas? Now we’re back to a scarcity economy, even with free energy, free material, and free production.

And what about time? Where are you going to get more of that?

Henry Ford thought if he could drive down the cost of production of material goods he could solve all the world’s problems. Didn’t turn out that way. Material needs can swamp others, because if you don’t have food and shelter not a lot else matters. But once you have those things, you aren’t finished.

Get those first 3 things on your list working tho!
