Are there laws to prevent owners of culturally significant artworks, e.g. van Gogh and da Vinci paitnings, from being destroyed, and from being shipped to countries that do not have regulations against them being destroyed? It seems the free market is moving in the direction of valuing destruction of art more than the art itself. In the absence of regulations, it would be a matter of time until some investor buys up a bunch of masterpieces, turn them into NFTs, destroys them, and ends up doubling their money in the process.
