They’re not making a technical argument but a practical one.
Who ever owns the chain is the ACTUAL owner of the NFTs. Who ever owns the physical hardware is the ACTUAL controller of the chain.
The problem with NFTs is … they only solve theoretical problems, not problems in the real world, where it ALWAYS takes agreement and cooperation for anything to ACTUALLY function and serve a purpose.
Blockchains have already proven to be no more secure than a properly designed normal database, and are ALWAYS going to take more electricity, so…they continue to be nothing but a toy and a canary for the gullible tech bro.
