"What you apparently did not enter into your analysis is that in F.U.B.A.R. mad max collapse, if you attempt to spend gold, you become a target for marauding gangs and also in any government haven a target for expropriation by the government."

let me read your palm ... you are fortunate to have made it into a totally collapsed world ...

I see you opening your door. The local "community worker" is there, and he asks for "your  donation"
to this weeks worthy cause - the junior section of the militia is upgrading to fully automatic weapons -
and he expects a brown envelope.

In 1000 words or less, write out how you will explain to him that you only have barley, wheat and
dried goods, and persuade him to either take those or to get the militia to restore your electricity
so you can transfer some cryptocurrency to them. Welcome to the new world.

@generalisethis - Things are going to go from bad to worse, as in Greece. The cause is excessive
fiat debt, caused by Central Bank policies. Bitcoin is the best remedy available, but once
economies ditch monopoly currency creation, allow zombie banks to fail (they are really only
Unions for the rich) then investment can get directed to sectors likely to grow or at least
collapse less quickly. At that point, as Hayek pointed out, there is no justification for Central
Banks, and as a consequence, centralised controls become inefficient and fail.
