Property rights emerge from the understanding you own your body and so own stuff you mix your body’s labor with.
But can you own an idea?
Lets say someone owns their idea. Then it should work like a house. They pass the ownership deed to their children and so on and so on. The idea never is able to be used by others without the owners consent. That seems harsh. An idea that someone came up with decades ago can remain protected if we treat the idea like a house. Even if the creator dies 80 years, if it really works like a house, then it can still be owned by people until the sun dies out.
And what if the idea is independently came up with somewhere else? What then? It doesnt work like a house. I cant take your house without taking ur literal house. But i can take your idea without taking the literal idea in your head.
What if an alien species with property rights is discovered and they have the same ideas? Uh who gets to enforce their ownership of the idea here?
Finally what if someone has the cancer treatment idea. They patent it and if it really works like a house then they can keep passing the cancer treatment ownership deed endlessly. So one business has a monopoly on cancer treatment for all time.
The counterargument is that no ideas will be made. But no one thinks about all the stuff that can be created if copyright didnt exist. And how ur denying people access to uss that info.
and its not like people are just gonna stop going to the original author for stuff like future books or movies. Some people will stick to the original creator because the creator came first and they respect the original creator for coming up with it first
