What you are suggesting is literally as ridiculous as shutting down California because of a school shooting in New York.
We're not talking about shootings. We're talking about an infectious disease.
A better analogy would be shutting down an entire company email system because 2% of the users of that system have been infected with a virus that spreads by email and is on the lookout for industrial control systems so that it can cause extremely expensive sabotage. Most corporate administrators would do just that in such a situation until they could deploy patches/signatures/etc to contain the spread of the virus, since so much is at stake.
Of course, the sensible thing would have been to set up a quarantine around a few villages when the problem first came up - that would have been pretty easy to do. However, as with most such incidents nobody wants to interfere with somebody else's problem until things are completely out of control.
The alternative seems to be to sit back and see what happens. Maybe that will work out, maybe it won't. I don't debate that there is a decent chance that everything will go fine if we don't do much of anything. However, this has the potential to be an incredible disaster, so I think that is about as wise as just hoping that another Cat 3 hurricane doesn't hit New Orleans, or that everything will work fine in 2038 without any code audits.
But, if everything works out fine the pundits will be out in full force saying, "see, I told you it would be fine" - just as many point to Y2K and call it a waste of effort. I bet they still own fire insurance.
