What do I want? For him to be thrown in jail. I honestly don't care about people swapping media between themselves. But setting up an exchange to do that, and paying for it by selling space to advertisers? That's not "sharing". That's business. And that business would collapse if he had to pay the copyright holders he depends on.
In general, audiences have NO idea how much time, effort, etc. it takes to produce decent work. Partly, that's by design, since good work should look effortless. But when you count the time getting good, a decent album may represent a decade of someone's life (10,000 hours, etc.) And the thousands of names in the credits of major films represent actual work, by real people. There's no reason these people should be expected to "find a business model" that doesn't rely on some form of legal protection when protection is the backstop of every viable business model in existence (not always legal, in the case of drug cartels; and where there's no protection at all, what you're really talking about is good luck and charity).
That said, I think enforcing copyright at the individual level is a fool's errand. No one writing the law - which evolved over centuries - ever imagined that it would be applicable on such a global scale, in such a granular way. Barring radical change in the law, I think individuals should be exempt from prosecution under something that is so spectacularly unsuited to free individuals and the democracy that depends on their liberty.
But corporations are another story. They're tools, not people, and tools have no rights. Shareholders have rights, employees have rights, citizens whose governments issue corporate charters have rights. But corporations themselves? No rights whatsoever. There's no threat to democracy in making them secure permission - by paying for it on fairly negotiated terms - or getting sued into oblivion. Indeed, that's the exact expectation around which the law and industries that pay for copyrights both developed. The Internet's appearance doesn't change the premise that anyone building a business around material they didn't produce, should include the properly negotiated price of their inputs in the prices they charge to others. Obviously, that's my own standard. It's not reflected in law. But I think it's a fair break. If it were reflected in law, I think we could put the copyright wars behind us for the foreseeable future.
As far as Kim Dotcom goes, it's clear he made his money on the wrong side of this line. That's why I'd like to see him jailed under law which should make jailing him a no brainer. I have no idea how he's going to pay for his current venture, but I'm pretty sure he says "safer" not "safe" for good reason. You'd have to be an idiot to give Mega the same level of trust that Dropbox enjoys.
