How do you propose ensuring critical security updates get deployed then?
Especially if an infected machine can attack others?
Users/IT regularly would never update or deploy patches which has its own consequences. There’s no perfect solution—but rather there to accept the pain.
Yes. But you don't deploy experimental vaccines simultaneously across the entire population all at once. Inoculating an entire country takes months; the logistics incidentally provide protection against unforeseen immediate-term dangerous side effects. Without that delay, well, every now and then you'd kill half the population with a bad vaccine. The equivalent of what's happening now with CrowdStrike.

It’s a lot like herd immunity in vaccines.
