Cracking down on piracy is totally possible. Pirates winning is not a foregone conclusion.
If you follow the torrentfreak blog you can see that anti-piracy forces really do make big moves. They are capable of passing laws internationally, international enforcement, dictating the technology in our devices.
So far things have worked out in favor of Pirates, but every year another piece of the cage is created, from device attestation, secure enclaves for decryption keys, infiltrating and busting piracy groups, shutting down the latest applications that people use, etc.
