Most reasonable people think it is okay to take something that doesn't belong to them without the owner's permission? Really?
Let me see if I can take another approach at the argument for your case.
People who participate in the legal copyright system, artists, producers, middlemen, the whole shebang... they are creating something with the express expectation of being paid for the creation and distribution of their labors. They are of the mindset that if you enjoy their labors, then you owe them some level of financial compensation. You may choose to call it greedy or selfish or wrong or whatever, you may cite the corruption and theft from within the industries themselves, or you may cite that art is meant to be culturally free or some other noble, heartwarming philosophical ideal. It matters not what argument is made.
If you choose to defend art (or any intangible intellectual work) as such, then only consume that which is produced for the sake of sharing and sharing alike, given freely with no expectation of financial compensation for your private enjoyment. If your desire is to do away with the copyright system, you are only harming the very cause you claim to champion by continuing to participate in it, which duplication and sharing without legal permission of copyrighted works is. You cannot disrupt a system in which you willingly support and enforce through your own actions, for better or worse. Two wrongs do not make a right, and your very actions only champion greater and more draconian laws from those you have taken from against their permission.
Further, given the expectation of payment for their works as this is part of their livelihood, from their perspective you are depriving them of their fairly earned wages. You are muzzling the ox that you have worked in the field. If it is your desire to owe nothing but love to others, participating in the unauthorized intellectual property redistribution of works protected by copyright leaves you with a debt greater than love.
I'm only 29, so I grew up in a time when 101% of all people my age downloaded music and didn't buy a single CD, EVER. So, maybe I'm messed up. I'm definitely not a "2 wrongs doesn't make right" kinda person, I'd align myself more with the "an eye for eye" group =P.
I suspect, like Reynolds, you have not truly thought out your position.
I don't know what sort of work you do, but let's say you're a programmer and someone commissions you to design some software work. You both agree on a price and royalties as they plan to resell the work, they pay a retainer, and you deliver the completed software with the expectation of not only getting the rest of the money owed for the work, but a steady stream of income from future sales to compensate you for the fact that you worked for a lot less than you normally would because you both know the software will be popular and used frequently. Just to up the stakes, let's say this deal brokered is the very thing that can permit you your financial independence, but that security does not come until after the work is finished and in your contractor's hands. It will be the pinnacle of your labors, and you have poured the very collected essence of your being into it as an accumulation of your wisdom, understanding, skills and talents. We'll say the contract stipulates that you get paid $100,000 up front as a retainer with the promise of $900,000 on delivery, and 10% of all profit from sales after distribution costs. The profit sharing is expected to bring in at least another $100,000 a year for the next decade.
They then proceed to take your work, and never pay you the remainder of your contract. Further, they then take that work and give it away for free. They have deprived you of the compensation you were owed for completing the work, and removed any hopes of steady income. What do you do now?
