You can really trade it as a token on some blockchain, and the data centre itself can read the chain (as long as someone sends it to them, but anyone can do that).
The data centre will do the bidding of whoever has the private key that's associated with that specific token on the blockchain.
But the whole blockchain bit isn't even necessary: some anonymous person on earth can hold the private key. When they want to pass on the rights to the datacentre, they send it a command (signed with their own private key) to obey some other key in the future.
Governments can't figure out who holds the relevant key. (At least not in theory. In practice, they can try to do classic spy craft and meta data analysis etc.)
So even though the owner of the key might sit in Germany or the US or Switzerland, those countries don't know that.
