The straight is narrow enough that they could use artillery to hit the ships in it.

And for US and/or Israel to prevent it, they would have to occupy the correspondingly wide strip of Iranian coast. At which point we're talking about a massive ground invasion (and of course then the same artillery would be firing at those troops, so you can't really just stop there either).

Or, you know, counter-battery systems and hundreds of patrolling drones.

During Desert Storm, US batteries returned fire before enemy rounds even hit apogee.

Desert Storm involved half a million troops on the ground. Iran is about 4x the size of Iraq and has more than 3x the population. The part of Iraq involved was flat desert terrain. Most of Iran is mountainous.

That's something ground-based. And to avoid counter-battery fire, tanks move after every shot.

The Arleigh Burke class of destroyers[0] might have similar capacity since each one holds 90 missiles in the vertical launch system[1] (so they might be loaded with anything: anti-ship, anti-sub, anti-satellite, anti-aircraft, ground attack or maybe anti-missile missiles). However, to reload those missiles involves several days in port. There are only 75 Arleigh Burke destroyers at this time. Not all are near the Gulf. It wouldn't be too hard for Iranian forces to fire $10k drones that require $1M missiles to stop.
