There is no argument clever enough or convincing enough to overpower the flood of money and bullshit that keeps copyright law the way it is. You may as well argue against the law of gravity. The only solution is to deprive the bad actors of the funds they need to keep the system corrupt, and since most people (rightly, in my opinion) can't accept simply abandoning large parts of their culture to that fight, the only option left is to make piracy widespread, easy, and safe.
