Well, here is the problem with your argument. You seem to be implying that someone who sells intellectual property for a living is entitled to that money to sustain himself
Uh, yeah. What exactly is the problem with that?
But no one is entitled to a living
I never said otherwise. If you can't sell your songs because your songs suck, that's too bad for you. If you can't sell your songs because people who would otherwise buy them are downloading mass quantities of them illegally, that's a problem for society.
And is cable service significantly different from intellectual property?
I would say yes. If you steal cable service you're not just stealing an idea or a song. You're actually using the cable company's property. Not that my heart particularly bleeds for the cable company.
