Yes I like that autocratic regimes, terrorist groups, and rogue states have a very hard time financing their operations. The meddling is certainly not perfect and not without collateral damage, but yeah I think most Americans are probably pretty okay with that.

Awfully suspect that people start coming out of the woodwork with arguments from “principle” coincidentally with them having a vested economic interest in a weak dollar/weak state generally (or at least thinking they have interests in those things).

Why do you believe any of that marketing? Rogue states? Terrorist groups? It's about power. If the US government cared about its people, then there would be real regulation to protect them. There isn't any because it's profitable to exploit them, not because of any libertarian ideal.

Meddling in the affairs of any corporation that handles just a single US dollar transaction is the opposite of interpersonal freedom. I am not sure how you can get this far into thinking about the subject while holding such a bizarrely cognitively dissonant belief.

These sanctions are frequently a point of negotiation against our adversaries. That’s my evidence that they matter. Unless you think they’re just wasting their asks on things that they don’t care about?

What evidence do you have for it being profitable (to whom?) to exploit (how?) the American people (by whom?)?
