4. Land ?

You can't be me, I'm taken

Ultimately just another reusable but non-renewable resource. Like silver.

And like silver one of some historical importance, but ultimately not so great as was ascribed to it.

I think land is likely to make a comeback, as I don't see food and transportation costs declining in any meaningful timeframe.

I wonder what the efficiency limit is for food?  a) Given free energy, how much land and resources would one person need?  b) What is the maximum conversion efficiency from raw energy to food energy?

In terms purely of calories, potentially fairly high. You can synthesize methane and ammonia from air, given energy, and you can combine those to make amino acids and fatty acids. Theoretically, all of this can be done adiabatically.

In practice, that's science fiction. But so is energy too cheap to meter.
