nonsense.
nearly immediately the following would happen:
economic activity would cease.
Power would go out
internet would go out
Water/Sewer cease to function
Transportation/Mobility highly restricted
Then it would be neighbor against neighbor for the last can of soup
Then mass starvation. The lucky ones would be refugees able to walk out of the most impacted areas, more than likely most would be kept pinned down in cities where they would starve, die of thirst and disease.
And at that point Im taking up arms not over ideology but to defend my gas-powered generator from thieves and my wife and daughters from rapists.
