Ignorance or not understanding the money transmitter rules is not a defense.
Focus directly on the entity doing the money transmission in this case- the smart contract IRON. They take in USDC and give out IRON and TITAN. IRON and TITAN are money substitutes. Money transmission includes anyone by any means conducting exchange of one type of money for another. Functionally that is what this contract is doing. The code didn't write itself, there are people behind it that released it, and they wrote it to conduct money transmission (a specific purpose). You don't even need to bring ethereum into the conversation to prove they are in violation.
I'm not sure I understand your comment about 'war on X' but I think it is a problem when there is an arbitrary application of these laws and unfair dealing that we see by regulators within the crypto industry. Maybe this is natural (self interest), and maybe it isn’t entirely their fault (limited resources).
I saw a twitter thread from a lawyer saying the SEC doesn't determine if something is a security, the courts and congress do. Then why are we obsessed with the SEC’s opinion? I speculate that we just need court cases and we do not need the regulatory authority to bring the court case. Maybe that is the problem to solve.
