Do you think any nation state has the will or ability to enforce anti-piracy laws within their own boarders, let alone on a geo-political scale?
If there is money to be made from the industry, and nothing is done to influence demand, all stronger enforcement will do is increase the violence and criminality of the people who engage in supplying the market.
So like, if you go after the moms and pops who pirate software and movies in china, organized criminal groups will step in to do it (which they have)
in this case, demand for almost as good quality product (lets not fixate on things like computer games and anti-piracy issues) for a much lower price is driving piracy. To end it, you need to create a population that no longer is motivated to want something obtained illegally for cheap, and an effective way to do this might in fact be to create scary international anti-piracy agreements that are nearly unenforcable.
EDIT: I could see more low end (like music downloaders or whatever) being charged so the government/law enforcement might fatten its wallet in this economic slump, but the problem is, most synidcates who pirate things have equal, if not better, funding and sophistication. Cyber crime like this is the freaking wild west right now.
