this is one of the few areas i feel like a blockchain-style solution could work. Mint a token, transfer it on sale or resale to the new wallet. Validate a wallet with the key is associated with the account. Same for old-school MSFT licenses or other systems where you buy a license key.
There's probably a shortcoming I'm missing here, but it's the only genuine case I could see a blockchain having use above other technical solutions
