If we're only talking about exploiting a device across a network, sure turn it off or disconnect it from the network. But there's more to security than that.

One can always take the device and turn it on for oneself.

If one can't exploit the device, one can resort to rubber-hose cryptanalysis.

Then bridge the gap by infecting pendrives. That's how e.g. Stuxnet worked.

I don't understand what you're replying to. Physical access is a great way to bypass network security, but it has nothing to do with websites.

"Exploiting device across network".

Security doesn't exist in isolation. AKA. there's always a way.

If you assume a specific target, there is always a way to get to them.

If you're talking about making a browser secure against internet-based attacks, there is not always a way. This type of security is merely extremely, overwhelmingly difficult.
