Post-scarcity nanotech, administered through 'manifolds' — consensual realities with locally agreed physics.

Live inside a chosen manifold whose rules deliberately exclude most available technology, because unlimited capability turned out to make an undifferentiated life unbearable. People restrict themselves in order to have a life with edges.

Manufactured scarcity — The abundance is real, so a new scarcity gets invented to compete over.

The most explicit treatment anywhere of scarcity chosen on purpose, by people who could have anything and found that intolerable.
