About entertainers, how could they live without income, and thus produce the entertainment I like?
Entertainers survived and thrived for thousands of years before the word "copyright" was ever uttered.
I care about property rights. I won't support a system that doesn't allow people to keep the fruits of their labor

It's up to the individual to decide whether he wants to forfeit his property rights
Reality check, it's up to whomever commands the monopoly on coercive force and violence. In this case, the nation state.
You have no rights, you have privileges granted to you by your masters. These can be revoked at any time. If you don't believe me, google internment camps WW2.
