No government have accepted Iranian tolls so far, that is just not going to fly ever. If every country controlling a strait started taking out such tolls that would cause much worse issues than we are seeing currently, nobody will have that.

No government has accepted Iranian tolls so far, but some shippers sure have; ships have been passing through the strait. Those shipments go on to countries with governments. I don't think you can actually know that there wasn't government support for any of those payments so far.

And cryptocurrency should be even better for deniability. In reality it would be a really good idea for certain governments that rely heavily on Middle Eastern oil (e.g. Philippines) to pay fees in the short term. More than a month ago the Philippines was already claiming to have "safe and preferential access", if that involves money they'll pay it.
