yeah...show me a surge protector that can protect against a few mega billion EVs of instantaneous surge.
Like the ones Hams use to protect their radios from lighting strikes on the antenna?
Like those, for example?
Not that hard.
The solution has been around for ten years now. Still expensive.
I suppose the government could deny the patent renewal in a few years to nosedive the cost.

The development in this field has been steady, despite the costs.
One surge protector, no.
Having a surge protector on each house's incoming line, that would primarily guard against lightning surge, wouldn't hurt.
