And artificial scarcity is just kind of... fine? We don't mind people intentionally destroying (or locking away) things just to increase the monetary value of other things?

Why would you assign malign intention to it? The facts are that there is scarcity and that where there is scarcity and demand then the monetary value will rise above zero. Just because someone can make something unlimited doesn't mean they should, especially to satisfy your desires - that's the job of you and your hard work or your wallet.

The same goes for the "it won't deprive you of anything" argument. There are plenty of things we all own that if someone borrowed it wouldn't necessarily negatively affect us, but that doesn't mean that we should lend them while we're not using them, especially not for free simply because it would satisfy someone else's desires and pocket if it were free.

There should be better delivery of items given the tech we have (it's better than it was but could be much better); there should be copyright laws that benefit the actual creator more, not just huge corporations (these appear to be getting worse); the price of media is often too high (though again, it's a lot better than it was); none of these are solved by pretending we could or should live in a communist utopia.
