If the internet shut down for even a second, there would be chaos. So many businesses, including utilities, and government rely on the internet functioning reliability. Many people would die.
With that said, what the proposal speaks of is shutting down small portions of the internet, such an ISP in a particular city. Not the entire country.
And moreover, it's likely even where internet access is "shut off", communications would still be possible for the authorities, utilities, hospitals, etc. Akin to how rolling blackouts are handled - to digress, folks who live in areas where rolling blackouts are common, but happen to be on the same grid as a hospital, police station, etc often still keep their power on - but not in the future, since smart meters allow remote cutoff of individual customers. Yeah for technology
The elites know their history ... "bread and circuses" - make sure the populous has food and entertainment. Turning off the internet equals riots and brings to mind the French Revolution.
