These are interesting discussions. The selling side is largely untested in a crisis scenario in recent history at least and would likely revolve around trade or barter in the worst cases; scenarios in which stocks, cryptos and the like would be utterly of no use. In more functional times as you say, various instruments offer various degrees of functionality and return. I do know that the few items that survived the prior generations of my family have not been in the form of equities or to some extent even real estate. Thanks for the thought provoking input!
