Money’s most important attribute is as a medium of exchange not as a store of value. There are too many forms of money which are too easily created for it to be a reliable store of value.
Spend it. By something with it. Gold an silver (specie), land, stocks, before it becomes worth less.
While I wasn't trying to make a point you're proving it, the fact that currency today is not a reliable store of value doesn't mean it isn't a critical component of good money.Fact is modern money is only a medium of exchange today because the government says it is not because people instinctively flock to pieces of paper with pictures of dead presidents on them. Think about it - If money is not a reliable store of value it will eventually no longer be a medium of exchange either.
