Is it also not "speech" if I use a mathematically defined mechanically engineered product's outputs to arrange my "speech" into ink-soaked shapes that is just a machine-generated output? Applying your signature (albeit a very complicated one) and hashing some numbers together with it is absolutely an expressive act of a human person. You can show your approval of what others are doing, or to suggest you'd like to signify someone else can now sign for your speech instead of yourself in a way others can see you are allowing them to have unique control of a piece of your speech. I think we've got it backwards. The freedom to provide credit or debit to others, noted in some record, is speech. It should never have been considered the purview of government to restrict free trade of speech containing negotiation of transaction or record of account. The government should also not be able to compel speech (especially without subpoena) or force private enterprise to conduct search of your effects and documents, so KYC should be out as well.
