There’s a good moral argument about dividing capital into land and other assets.

But I suspect that from an economical efficiency perspective that division is less interesting than between revenue and assets.

It's really more about dividing capital into the kind that is "natural" and limited - land, mineral rights, EM spectrum; some would also say copyright and patents - and the kind that is produced by human labor. It's a bit fuzzy in practice.
