Actually its the opposite. Digital media makes it far easier to copy, redistribute and modify, hence why there's so many restrictions placed on it.
If I wanted to sell my Beatles LP I could do it no problem, because reproduction of it (now bear with the metaphor here) is more difficult and time consuming. Hell, even bootlegging it (which is illegal) would be an order of magnitude more difficult because I'd need to set up the equipment to do it and there's a cost of of entry associated with that. Scarcity of supply affects demand yadda yadda.
Digital? Just a few clicks. That's their problem. The fundamental shift to digital media has removed all these barriers hence completely removing scarcity from the equation. They can't control the scarcity. They can't control their product. Once its out that's it and that makes it fundamentally "worthless" in their eyes. And so here we are with laws passed that try to fight the inevitable: helplessly maintain control of their withering walled garden.
Don't pity them. These motherfuckers don't deserve it. Not with how they treat their artists like cattle, or how they happily got away with printing albums with one good song and 13 dogshit tracks. Now they try to muscle in on live shows which are the only way artists make money.
