One step above the "small community of off-the-grid preppers" would be to come up with ways to make today's societies more resilient to systemic hick-ups, small and large, using either the means available already today or those which are very close in the technology tree.

Doing so would require a lot of decentralization, e.g. by localizing production of electricity and other consumables and making these smaller units more autonomous. Think not big cities with a power plant each, but rather groups of houses sharing solar panels and a wind mill.

Then again, this would probably be a kind of a pipe dream, as decentralization is by definition not completely under centralized control. This creates all kinds of friction. For example, if everyone produced their own electricity locally, what would the power companies do? And what would the state do with the lost tax money? There are plenty of problems like this, and I doubt one can find a win-win situation where the nowadays centralized things would not lose in some way.
