Without copyright law, someone else could grab my novel and start printing/selling their own copies of it.
You should look into Creator Endorsed.
Only asshole people will buy from a rip-off publisher. But asshole people will also elect a government that will enact things like a DMCA, so they're going to screw society either way as long as they have the government stick to wield. Not having the government-enforced copyright also eliminates problems like this Samsung* one, so you get multiple benefits from that strategy. It's risk-management, not risk-avoidance.
* guess whose phones I won't be buying again in the future?
