No, you're wrong. Let me repeat: moral norms and justice systems universally stem from property. This has always been, and will always be, because we exist in an environment of scarcity, and
property is a construct to reduce conflict over scarce resources. In a world where resources are infinite and instantly accessible, property doesn't exist, and therefore neither does morality or justice,
because there is no room for conflict over scarce resources.
The root concept behind mutually voluntary exchange (or what you're calling "fair trade") is
property. When two parties exchange, they are exchanging
owned scarce resources. At a bare minimum, they own the scarce resource that is their body, and they own the scarce resource they intend to exchange. This is elementary economics.
My point was that this framework develops automatically, spontaneously, as a necessary fact of the human condition. Humans naturally value property as a means to reduce conflict within a reality of scarce resources.
The root premise of government granted monopoly privileges (of which IP is an example) is the use of violence or threats of violence to restrict what people (who aren't given the monopoly grant) can peacefully do with their property. Obviously, peaceful people don't value this, and therefore all of history managed to avoid its institutionalization, until VERY RECENTLY when governments began imposing itand what else would you expect, from
institutionalized monopolies on violence.
So don't get involved in a philosophical discussion and dismiss the opposition as "semantic". And don't try to rationalize IP via morality, because it flies in the face of everything morality is based on. You don't use violence to intimidate peaceful people, and you don't treat other people as your slaves, deciding what they can't do peacefully with their property.
