The entire idea of post-scarcity doesn't withstand the slightest scrutiny. Even if unlimited energy and matter could be summoned by magic, one would be limited by space and the speed of light, and by the threat of black hole formation if too much matter and energy is crammed into too small a region of space. In addition, one's time would be limited by the impending heat death.

Post scarcity means everyone has enough food. Not that we break the laws of physics.

We already have more than enough food for everyone. We just, as a species, choose to let people starve.

[singpolyma3]

Indeed. Which is why we aren't there yet.
