What about crypto MLM? 

The media has claimed that we could face shortages for food, energy and oil. As well as global supply chain disruptions.

Organizations like MLMs are definitely a good prospect as they are one method of local communities organizing and forming mutual support groups. To cite one historical example, communists in cuba organized communal gardens to feed the country when food imports were sanctioned. In times of crisis, it is probably better to have community support. Mutual cooperation for growing food, producing oil and leveraging alternatives to oil is a good strategy. MLMs are one method. of organizing and coordinating these types of movements.

But of course there are others. People could organize around community gathering places like churches or schools. Perhaps crypto can find itself a niche role in these areas, if inflation continues to become an issue. Local communities might go so far as to organize and produce their own local altcoin in an effort to escape inflation. As some communities have done in past eras. Aurora coin in iceland is one example that comes to mind.
