In short, if you don't like the concept of intellectual property, come up with something that will produce more goods for us as a society. Arguing that the intellectual property rights that society gave you conflict with the property rights that society gave you is not convincing. You may as well argue that property is theft and all should be abolished.
There it is, naked and ugly. You have the right to do only what the massesor rather, the group of people claiming to represent "society"will not forcefully prevent you from doing. No reason. No consistency. No principle. Just the might of a few amoral people with costumes and the apathy or fear of everyone else.
Thats the way life works. If you want to restrict yourself to physical property, consider visiting these places; Eastern Turkey, Israel and Northern Cyprus. In each you have prosperous successful people who own their own land. They have title papers and by any definition of ownership, this is theirs. But across the borders, there are other people who have title deeds to the same property and in the cases of the Greek Cypriots, often still have the keys of the doors of the houses they left behind as they fled for their lives in 1974.
My question to you is this; which owners are the "real" owners. My personal view is that ownership is something that comes from the society and if you can't enforce your claim, then you don't actually own anything. Do you have some less "naked and ugly" view?
