DRM is enabled by copyright law. DRM only works because talking about how to break it, and collaborating on tools that enable breaking it, is illegal - because of copyright law. DRM relies on giving people the ciphertext, and the decoder, the decryption key, and a way to use those to recover the plaintext, and trying to prevent them from figuring out the decryption key for themselves. Without copyright law backing it up, it's toothless. Get rid of copyright, get rid of DRM. Also, EULAs are only enforceable due to the fiction that running software without accepting one is a breach of copyright. Without copyright, EULAs are pointless, and anyone can write and distribute tiny programs to patch out EULA acceptance screens or license key verifiers, because copyright law won't prevent them from doing so. Get rid of copyright, get rid of EULAs.
