I'm fully aware that the law recognizes what is colloquially referred to as "intellectual property". I don't discount the ethicality of "intellectual property" on a whim, or because I want stuff for free. I discount it because [b]it's not ethical[/b]. Yes, it's the law, but it [b]should not be[/b]. There is no physical component to "intellectual property" that can be controlled: every time someone reads something that has been copyrighted, a copy has been made. The concept of "intellectual property" does a downright crappy job of accounting for that because it's conjuring a body of law from thin air. There is no empirical basis for ownership of ideas.
Your statement, "Just because you don't recognise the concept of intellectual property, doesn't mean the world doesn't," is nothing more than an appeal to popularity. The fallacy of believing the validity of something based on how many other people believe it is a very tempting mistake to make, but it's still a mistake. If nobody ever believed anything that conflicted with popular opinion, we wouldn't have modern science.
"If there were no intellectual property there would be no copyrights on music, art, literature and software," you said. My answer: Good! Copyrights and patents should be abolished.
I don't "believe in the rule of law," actually. I believe in the necessity of ethical action. I believe that any law that isn't ethical is invalid. The "rule of law" is, itself, of no value if it doesn't involve ethical laws. In fact, where unethical laws exist (for instance, legal slavery in the early nineteenth century), the "rule of law" actively does harm.
By confusing the issue of property rights, by artificially constraining the freedom of action of those who do not act unethically, and by creating additional unneeded complexity in the law that can be abused, "intellectual property" law brings harm to individuals on a daily basis, even if they don't realize it.
I don't pirate software. I don't trade MP3s online. I'm pretty much a law-abiding citizen, where intellectual property law is concerned (though not so much where speed limit laws are concerned). I observe the restrictions of these laws because there's a great big government hanging over my head, ready to enforce unjust laws. I also do so because it's easy to observe such laws: I just use free software almost exclusively, and though I could burn MP3s and movies to CD and DVD, I prefer the higher quality professionally-made CDs and DVDs and everything that comes with them (including lyrics, a second DVD full of extras, and so on).
So: You're wrong on every count. Your two main points were "Intellectual Property Is Good!" and "You (meaning me) Are Bad For Not Observing IP Law!"
1. "Intellectual property" is not good. The fact that it's enshrined in law doesn't make it so. The fact that lots of people think it's good doesn't make it so. The fact that major record labels and Microsoft make money hand over fist by selling duplicates of something that they hardly spent any money on directly doesn't make it so.
2. I observe copyright (and even patent) laws, probably more strictly than you do.
So, in summation: Stick a sock in it.
