I suspect you are right. No food deliveries, no ATM cards, no nothing. That could possibly starve millions to death. It will get UGLY in a real short time.
When transportation stops, grocery and supply stores will be empty in 3 days max.
And neighbors burning each other’s houses down with bullets flying everywhere as food & water run out.
Shelter in place means you will die.
The Blue Hives are just Democrat vote-harvesting plantations today. The more govt dependent they are, the better, including low-IQ illiterate illegal aliens (future Dem voters.)
But low-IQ people who depend on the govt to feed their (illegitimate fatherless) children breakfast, lunch, and dinner (school, school, EBT) are not going to be much use to Team Tyranny in the event of a CW.
They are just dead weight. They will burn down their own cities when the food, electricity and water stop flowing in.
