A notional monopoly on violence is important, but even in a police state it just isn't enough. You must achieve a broad consensus that, even if this isn't good, it's better than the alternative, and if that ceases to be true in the minds of a great many people their alternative is going to assert itself right quick.
You think most people living under an oppressive regime think that there's nothing the government could do to be better? Such a state doesn't need broad consensus that there's no better alternative, it just needs to avoid the consensus that the personal cost of attempting to achieve the better alternative is worth it. That's where the monopoly on violence really helps.
No there’s no solution. Not until we all fully operate in a legal realm (the/a metaverse) that validates the contract and rewards the humans who created the contract to cover their own ass. If the contract doesn’t follow the _legal_ language and intent it’s not smart at all and yes it’s totally a solution in search of a problem.
this NFT stuff is doomed to failure until we all operate in the same realm validating the identity of the contract owner, validating the legal intent of the contract, because that’s what a contract is in meat space
Intellectual property is another thing entirely, and not as easy to enforce, especially in the digital age.
