As Nomads who aren't in the sticks & bricks (full or part time) it's important to consider one's own safety. If we didn't learning anything from the height of the Covid 19 event we did learn to seek out areas where our safety would best be assured.
Those whose rigs have solar & house batteries (or perhaps a generator) may be more self sufficient than those on the grid, but when people are afflicted by a disaster without power, water, food etc and are out hunting for resources at any cost, how safe from that would you be ? So being aware of your surroundings may be your best plan B.
