you'll find that in actuality there are a lot, if not mostly, U.S. dollars in regular use as well. (Stilly River Sage, emphasis mine)

Why are you defending a wrong statement of fact with new nonsense instead of simply admitting an error in a minor detail?

I recommend a look at a site with travel tips for Israel (U.S. dollars in cash are accepted at a limited number of shops you'll find for instance). And even if the information was true what would it mean? Sites with travel tips for Iran state that US dollar is accepted as cash nearly everywhere in Iran. Do we learn anything from that? No.
