I guess it is a good thing then that this isn't something they actually do.
They use cheap weapons to shoot down cheap drones. Their primary anti-drone missile was developed in the 2010s and costs less than a Shahed.
The US took the old Vietnam-era unguided rocket pods (Hydra 70), of which they produce hundreds of thousands every year, and slapped a dirt-cheap guidance kit to the front of each rocket. Supposedly 90-95% effective. A bunch of countries are developing their own clones of the concept.
A single F-16 can carry 42 missiles. They've been rapidly expanding the number of platforms they can attach these to.
Which is the same reason no level of military power is going to keep the Strait of Hormuz open (or at least, no level beyond a truly absurd one and even then - see the Kerch bridge in Crimea).
But Orange Dementia didn't even think about that.
