In cryptography there should be exactly one copy of a private key in the entire universe. When your keys leak due to a mistake or whatever, you invalidate it and make a new one, you don't sue anyone who might have a copy in order to get them to delete it.
When was the last time you ever saw that happen? Some work you grew up with enter the public domain? These companies have already made untold fortunes, several times over. So why doesn't it happen?
They altered the deal. Unilaterally. The money people paid them? They used it to hire lobbyists to change the law and rob people of their public domain rights. These monopolistic protections were meant to be limited, they had an expiration date. The corporations managed to extend copyright duration to the point it might as well be infinite. There exists a public domain but no work ever actually ascends to this mythical place. Fair use? Nobody without an army of lawyers would ever dare try for fear of being sued.
Is this the social contract you want people to respect? The one where they get everything and we get nothing? You say my view is one-sided? These corporations are the most one-sided monopolists there are.
The second people stop pretending artificial scarcity is real, it will be the end of them. Look at how Sci-Hub is shaking up the academic journals. Their end literally can't come soon enough.
But for the most part you are right.
The key fact here is that numbers are just the means of content delivery in a digital world. To be clear, personally I'm not fond of Copyright status quo, but this particular logic makes zero sense.
