It appears to be true with fact checking here

“The claim is indeed true that Iran has offered ‘full right and freedom’ to transit the strategic waterway if Arab and European nations sever ties with the US and Israel, as per state broadcaster IRIB.”

This statement was made live on BBC but the report seems to be true, here are some links.

Perhaps look up Uncanny Valley. It is similar in ways to what you are describing.

I read somewhere that Iran can close the strait without a full-scale naval engagement using selective drone strikes and harassing vessels, Iran triggers a spike in maritime insurance premiums which will choke shipping companies. Also because of the narrow width of the strait, also shallow, Iran can use mines, they have both simple contact mines to sophisticated “smart” mines, apparently they possesses one of the largest naval mine inventories in the world.
