I think this can help to verify ownership across national borders, yet I think it might require global governance to overlook the enforcement of these property rights, which I haven't heard too many people discuss.

Copyrights, patents, and trademarks in the US, AFAIK, are basically just the right to sue someone if they infringe on your ownership rights. Even deeds and property ownership require some legal or physical enforcement.

Anyways, I'm curious about this space and hoping I start to hear more conversations in crypto talking about which systems of human governance we want to work hand-in-hand with these blockchains.
