There's definitely a slope, and trade-offs in both direction.

In the case of land, there's an absolutely limited supply of land, and so I think it could be argued that, in balance, it's more important to make sure that limited supply is used effectively.

Gold, by itself, isn't actually very useful. If someone wants to hoard it, they'll increase the market price for it, and maybe luxuries like jewelry or electronics will be more expensive, but it won't affect much.

I'd actually argue that patents that aren't being used should be made public domain. There's only so many good ways of solving some problem, and if society is blocked off from using some or all of them, then society is that much worse off.

If used as intended, to protect the results of invention/research until a product is brought to market, a patent's downsides are outweighed by its benefits.
