You go through all this trouble to prove that blockchain is useless and yet keep coming up with examples where it's useful. Too much to respond to but this point: "Well that's funny because if you use DocuSign you will be connected to someone that will verify your official ID, and verify that it matches your face." Here you describe "Docusign chain" which does have the property of linking ID to public id/key and is useful.

But it's better that Docusign describe their use of blockchains, since 2015, in their words https://www.docusign.com/products/blockchain. Pretty sure that invalidates your conclusion, too, "As explained above, blockchain doesn't solve that. Blockchain literally does not solve anything"

Docusign is a centralised trusted 3rd party which performs ID verification and holds hashes of signed documents. This doesn't require blockchain. They were performing this service before they offered anything related to blockchain.

You should read the link you shared, because it would become evident to you that they offer customers to connect their Web3 application to DocuSign, not that they rely on blockchain for their service.

But they use Blockchain which in turn makes it useful, do I really need to spell this out.
