When the food runs out, it is 3 days too late for the revolution.
But food running out isn't the problem you are talking about. You are talking about the failure of the logistics of the supply chain to grocery stores. Those stores carry a 3 day supply for their area, and most people are 100% reliant on them. And if they fail, the towns go hungry. Therein is the single point of failure.
Our mitigation for that is to split the food supply for our family in thirds... we still buy about a third from stores, like everyone else. We grow a third ourselves, and we get a third from other farms, some local, some remote from whom we ship things in monthly.
It is completely feasible to diversify your own food supply. If everyone did it, we'd still have pains if the supply chains failed. But they would be survivable pains.
If the grocery store supply chain falls apart, it is unlikely you will be able to get any food from afar for the same reason (or, at very least, the people normally performing the deliveries will be too hungry to provide delivery service). Local farms are going to want to hang onto their production for themselves now that they have no other food source.
Realistically, that leaves the food you are growing yourself. 1/3 of your normal intake does sound like a struggle already, but to compound the difficulties, you have to ensure that you have the food available when you need it which is more complex than setting up a garden. Not impossible, but certainly a lost art. I'm not sure it really is feasible to expect many to follow through with this.
