And how exactly would they "defend" us against an airborne virus? Give everyone gas masks? Hazmat / hazchem suits? There is only so much preventative measures one can take against a theoretical happenstance. It's easy to say that government or X agency isn't doing enough - what is difficult is giving reasonable suggestions as to what could be done that they aren't doing.
Something like this:

Offered as an opt-in, so no one was forced to participate, eventually bringing more commercial infrastructure (like shopping malls, etc.) into compliance, so one didn't have to leave the security of the network in order to live a relatively normal life.
I understand that many wouldn't want to give up cars, boats, trains, and airplanes so readily. Yet at the same time, I know many young professionals that would gladly jump at the chance to participate in such a new model infrastructure, and it just doesn't seem conscionable to leave EVERYONE defenseless just because a majority of stubborn hold-outs never want to change.
Especially since the CIA have issued reports saying this is the ONLY option that could defend against this threat, and we need to shore up defense spending to do this if we are to survive. That was almost four years ago when Obama took office.
That is something we COULD do relatively easilly. As pointed out in the article, it is also the RIGHT thing to do, considering the troubling trends of our modern outsourcing and increasingly automated economy. Humans are becoming obsolete and eventually, SOME new standard will need to be develloiped to address this. Otherwise we'll have massive nationwide homeless camps before we know what happened.
I don't see digging holes to fill them in to justify giving man a paycheck as a solution, or in anyway helpful to our future, nor will it address this most critical threat we have ever faced. This secure public housing and food/medical/water ration program does both, and does so in compliance with green energy standards.
It just seems insane not to offer those that would choose it an option. Then let the people that want to drive down all yesterdays roads with the top down do so if they choose to take the risk. But don't leave everyone behind because of the attitudes of the majority.
It is actually quite unprecedented. This is the first generation of humans that has faced a new threat of such an overwhelming nature that we simply threw our hands up and quit trying.
