Should You Copyright Your NFTs?

For example, I could mint a new NFT with any CC0 Noun, but because everyone knows the “original” collection, the one endorsed by the creator(s), mine will have no relevance and probably little if any value. But the opposite could happen, too. A creator could launch a collection with incredible art tomorrow, but fail to get any attention and sales. Someone else can “steal” the art, copy the idea, rebrand it and profit from the original work without being required to compensate the “original” creator. Copyright gives you the power to legally sue someone using your IP without permission. CC0 doesn’t.
