I agree. Hardware switches should also be put on computer cameras, microphones, network cards, etc. There will still be vulnerabilities, but most of us use lock

I agree. Hardware switches should also be put on computer cameras, microphones, network cards, etc. There will still be vulnerabilities, but most of us use locks on our house and car doors even though thieves can (and do) break the windows. Hardware switches on computer equipment can remove some vulnerabilities and (sometimes) add a means of recovery.
