First of all, civil courts are supported by the civil law, and that law is supported by the government. One example of a civil law is copyright enforcement, which is often enforced by the Supreme Court.

And also, when actual powerful entities (whether that be governments/corporations/etc) start to involve in protecting NFT investments using the law, is there any benefit of "crypto" being used to protect the value of the asset anymore? Isn't it just private property with extra steps?

I really don't think the Mona Lisa comparison doesn't fit with the current conversation with NFTs, since NFTs deal with digital assets, and trying to convert an analog artwork like Mona Lisa to fit into NFTs would already demolish its authentic value as an amalgamation of detailed, non-reproducible paint strokes (which I think is the authentic value you're emphasizing about).
