You can imagine why that's a non-starter. You'd be locking millions of people out of their Internet access with no workable way for them to get it back.

Just imagine how many scammers would pop up to 'secure' things for people locked offline.

What you're proposing is a massively worse ddos vector than anything seen so far.

Hacking a webcam would no longer lead to the ability to ddos websites, it would be a direct and total shutdown of the domestic internet supply.

No it shifts our priorities. Once people realize they can't access 90%of the internet unless they reinstall their OS or unplug all network devices, people will become more vigilent.
