I agree with you. However making a resource artificially scarce to push the price up is what humans do. From where I am sitting I can see multiple items where this happens gold, diamonds (wife's ring), water (in a glass) electricity (well, a turned in light), several things with brand names on them (the copyrighted logo seems to keep that price up by ensuring that only one supplier exists, keeping supply low). I'd be quite surprised if there was much in the room which wasn't artificially price inflated.
Sort of but it's not exactly the same thing. Physical items generally take effort to build or to extract, and they generally pay for the land or materials or whatever. Copyright is meant to artificially inflate the value, for the benefit of the author who wrote it.
If there is a case of someone just inflating the price and adding literally no value at all then I would say that is just as bad.
