Isn't this like the #1 use case for crypto? Everyone wants an untrackable unblockable currency that is out of government control until the day it is used for things they don't like, then suddenly "government please control this!"
I thought the #1 use case for crypto was ransomware, followed by shitcoin rug-pulls, and the ability to commit theft without recourse. Sending money to Iran is just a minor edge case.
As far as I know, nowhere in the Bitcoin white paper or the original code base. Does it say anything about what you seem to think it's use cases are.
Bitcoin has one main use, digital cash, that can be sent instantly and for free or a very low fee.
Edit: I would agree though, that anything other than that is probably a scam.
