Sure, but the abolition of copyright would also mean that individual authors do not have copyright over their works, even if they sidestep the publishers. (Which, to be fair, the commenter upthread admits - turn on showdead in your profile if you want to see it.)

I am not sure that many authors who get mistreated by their publishers would feel like they're going to get paid better and have more control over their creative output if copyright goes away entirely.
