Exactly. The US just announces that they will take any vessel that pays for transit. So, what happens then? Any vessel that goes through and the IRGC doesn't shoot them, the US seizes. So, no one pays since they can't pay for successful transit. The fun game is that all the vessels just go at once. Any that the IRGC doesn't shoot the US takes. Any that it does shoot sink. So, no transit. Unless IRGC doesn't shoot at all, in which case everyone gets out of there with just one vessel paying the ransom. Ultimately this doesn't work for the IRGC as the US is far more capable of closing the strait than Iran is.

The US can also fuck with Iran by getting slight cooperation from ships in the Gulf of Oman by getting some small inflatable boats with remote control and AIS transmitters on them. Put the boat in the water next to a ship, turn of the ship's AIS, turn on the boats AIS, and send the boat through. Send hundreds of them. IRGC won't know what to shoot at or will expose their positions by firing at a rubber raft.
