It is even harder living without money in climates with pronounced winters. Edible plants disappear and people must pay for heat or freeze to death.

Your question is about what communities must do to survive without money.

I believe that the best answer is to create informal systems that engage in barter and charity.

In a barter economy people simply use the stuff they have as money.

I threw in the word charity. Sadly, most of the people who engage trading used products are out to take everything they can from the people with whom they trade.

For a barter community to work people need to have a charitable mindset and intentionally act to engage in fair trade.

A blockchain can help people in barter communities. A blockchain is essentially an open ledger. People can record their trades on a blockchain.

I suspect that HIVE is particularly useful as one can work in different tokens as they engage in trade.
