Be careful what you wish for. Repealing copyright without also making DRM and EULAs illegal would probably do more harm than good.
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.
EULAs are obviously bogus though, yeah.
