It's the 21st century, nothing stops us from simply copying works with absolute impunity. The question is why even recognize copyright as legitimate to begin with?
Society is doing creators a favor by pretending their works are artificially scarce. We allow creators to profit from their works. Public domain is actually how things are naturally: after data is created, it can be copied infinitely at negligible costs. We enable the artificial scarcity that allows creators to profit from their works.
There has always been an understanding that eventually the works will return to the public domain. Creators are supposed to make money for a while but eventually the party is supposed to end. We're not here to enable their eternal rent seeking. If they want more money, they gotta make new stuff.
Every time copyright duration is extended, it's a slap in the fact of the public. We have been blatantly robbed of our public domain rights. No one's ever been bold enough to suggest straight up eliminating our rights though. At some point copyright infringement becomes civil disobedience and a moral imperative.
