Lobbying by Disney is the reason for it.
When you invent something in the US, you file a patent application with the USPTO and after arguing with them for a while you may eventually get issued a patent. Your patent expires 20 years after the date you applied (which may be years before the patent actually issues). So you can expect somewhere in the neighborhood of 16-17 years of protection for your patent. After that, your invention belongs to the public.
If someone violates your patent, it's your responsibility to find them, notify them, come to an agreement, or sue (you gather all evidence and pay all legal fees). The government doesn't even get involved unless you take them to court over it. If you take them to court, a jury may award you monetary damages for their infringement of your patent. That's it, nobody goes to jail, you get handed money (if they don't file for bankruptcy).
Copyright on the otherhand....
Is something you have inherently. No need to file it with the government (though you can register it with them for extra visibility). I have a copyright on this post... I don't necessarily even need to say so. Your copyright lasts 70 years beyond the life of the author. A typical copyright will last well over 100 years. You pay no registration fees, there is no application process.
If someone violates your copyright, the FBI can prosecute the case with your even being aware. Sentences for copyright infringement include jail time as well as financial damages paid to the copyright holder and the government.
Now tell me.... why should copyright and patent be different at all?

Unless I'm mistaken, some musicians flat out encourage piracy.
Many just offer their albums for free on their website and expect that people will like their music and attend their concerts, buy their merchandise or whatever else. It's worked for Radiohead and KoRn and I assume many others.
