It's our job, though, to make that available and easy for creators (e.g. kudos to RMS for making and popularising the GPL).
But no one should be able force anything on _all_ creators.
PS: Well, the outcome would be that creators would stop create at all, and in some cases that might be fair and just, but that's another topic completely. E.g. some societies regard as fair and just limits on drawings of humans and animals, so there's no such drawings. And they see it as fair and just.
But demos doesn't mean "we, consumers" -- it means "we, the people". As in, the body politic, from whom all laws and therefore copyright ultimately emanates. Creators only have those copyrights because we've granted them. This is a law of man, neither God-given nor a law of nature -- we can, if we want, un-grant them.
Creators may choose who to sell to, with you there. But then we (the demos) may choose to not give copyright protection. We're not limiting creators freedom, we're limiting who we choose to protect from the open market.
