Self-ownership means ownership of your labor. Since I don't own the ideas, but my labor, I have very limited rights of ideas. I cannot prevent you from thinking with my ideas, because you own your own mind, and I cannot have full sovereignty over HOW an idea is used. Since labor is all I own I can basically only own the rights to economic exploitation of the ideas.
Own the legal rights to economic exploitation of the ideas? If I sell an idea that you've created, that would be illegitimate in your book. Getting gold coins in return for "selling" your idea would be wrong. How about using your idea to physically create gold coins? How about using your idea to physically create chocolate coins, which I would could eat? How about using your idea to prevent falling in a ditch? How about using your idea to create stone figures which I later trade for a big log so I can safely cross the ditch? Please define "economic exploitation".
In fact, over the centuries various things have been proclaimed as property that we today consider alien. Take slavery. People were indeed property. A slave proponent could argue that you should leave his property alone and that the term property is already taken. In a rational world that's not how things work.
In a rational world that's not how things work because you would own your body.
Nope. Ideas are not property. Intellectual labor is property. No-one can own an idea without creating a totalitarian society.
If ideas are not property you cannot own your idea. Labor != property, but you can use labor to create property. You own your labor, you own the object you created, but you don't own the idea.
If you used 10 years of your life to figure out how to walk backwards, I won't pay you for it.
If you don't sign a contract with another person explicitly stating not to, it's ok to kill him.
Why would you even suggest something like this? I know you agree that you own your own body and therefore do not need a sign.
But what if someone actually spent 1 billion dollars researching and inventing Aspirin and after 10 years of hard work and lots of investment ...
Why is "10 years" and "hard work" relevant? Do you believe in the labor theory of value?
But if for some reason that principle didn't include rape when you walk alone in an alley, then I absolutely positive that you wouldn't have felt an inch of sympathy for the poor woman, just like the gang rapists don't feel bad for raping her and beating her half to death, and I find that pretty scary.
Again, all the posters here agree that you own your own body.
It seems like most of your analogies don't work.
Other than that, I applaud Onarchy's initiative, although I suspect there will be a lot of debate on certain issues like IP and FRB.
