Creative art, i.e. media, is not the same as a tangible item. Let me give an example. If I say something to a friend, is it a crime for that friend to write what I said down and repeat it to all of his/her friends? Think about it. It's ridiculous. If you don't believe in filesharing, don't do it!*
*I don't.
Your analogy doesn't stack up. If you spend a good amount of time working on an episode of media which requires writing, producing, acting, etc. And it is intended to be sold, and it's income is based on the number of people watching, it is simple theft to copy it and give it to others, whether or not you make money on it.
Nothing is produced for free in the world, and suggesting that just because people are working and making money in a digital world which is not policed as diligently as physical theft is that it is somehow OK.
The entire software industry has suffered with piracy since its infancy. Copy protection schemes are usually not effective. Moral compass is something which must be taught, and people should know that theft of anything, physical or digital, is wrong.
