The US could/can, they're just not willing to undergo the mass casualties it would take to put boots on the ground and put those boots up the ass of the people controlling Hormuz. Which absolutely cannot be achieved purely by air.
If you cannot afford doing it, then you cannot do it. What's the purpose of having the capability to do something if you cannot afford the losses of doing it?
This is just a different way if saying that we can't.
US military ain't some unstoppable force in all possible scenarios, it was stopped and won over quite a few times, last time I recall by taliban sheepherders. In some cases like first Iraq war yes, but they don't wage those wars anymore. And all mental limits re casualties are very real limits just like other.
Its like saying russia could/can conquer whole Europe, if only X, Y and Z. That effectively means they can't, as we see playing out right now despite them trying desperately to achieve this very thing.

It doesn’t matter what the reason, if you can’t do something you can’t do it.
