The ability to create infinite copies for essentially zero cost changes the utility calculus significantly.

If we're talking about physical property like, say, a single-family home, the only question is which family is allowed to live in it.

If the physical world worked like copyrighted creations, we'd be able to give every family on earth a copy of that home to live in, for free. And while that would still have downsides for the heirs of the builder (with infinite supply, they could no longer rent out their own copies of the home for a profit), the total utility gained by humanity would easily justify that step.
