You game nft example absolutely does not need nfts to work. Heck even old school serial codes would work just fine for this scenario (steam accepting serial keys to allow access in their system). It also does nothing to solve the fact that NFTs hold no legal power and do nothing to resolve the issue of IP ownership (steam can't just start giving away access to Epic games because they feel like it, they need to negotiate and buy the rights or permissions from epic and their partners). For the North Korea / US businessman case - I literally cannot come up with any scenario where legal jurisdiction or some external force (police, lawyers, asset seizure) is not needed to enforce the contract. How will the computer know the contract has been breached? Who's going to tell the system what the breach is? Give me an example and I'm happy to reconsider. Meanwhile, in reality we have a system for this, where judges and lawyers make those calls, and enforce them with the help of police. There's a reason why cross-border deals are risky (enforcement), and no computer is going to solve that.
