IANAL but some spam junk encoded would not satisfy the requirement of delivery of process. It also does not bind to any address, so it has no meaning. As soon as the “owner” address destroys the UTXO, address is meaningless and binds to nothing, the key is “lost”. You can’t query it without scammy third party hallucination websites. Ordinals don’t exist.

Forgive me some shitcoinery for a minute, but I want to contrast how absurdly stupid and scammy the ordinal idea, let alone process and expect a legal binding.

A much stronger case can be made for an ERC20 style NFT to a publicly known EVM address, in that it could bind to a person, and active transactions from that address demonstrate active private key knowledge in the accounting model. Contract calls can be made without any special tools and would return a url, possibly ipfs url. All without special on proprietary tools.

Which is also bullshit, but this ordinal delivery of process is double bullshit and would not satisfy anything anywhere. Utter nonsense.
