In all the above, the references to money should be changed to fiat-USD or some other fiat "currency" which has no inherent or otherwise intrinsic value.
Note that anyone who has the forward thinking and volition to turn some of his fiat currency into real money, gold and silver for example, will already have solved or mitigated the food/water/security, etc aspects....and is probably already in south america or some other country with minimal government reach. However, there is no government on this planer that is anything more than a criminal gang.
If someone has gold and has to trade it for water, he probably stole it.
A character from William Shakespeare's play Henry VI, Part 2, Act IV, Scene 2 had a novel idea: "The first thing we do, let's kill all the lawyers"Way back when I was doing contract work I had the luxury of picking who I worked for. There where 3 groups of people that I absolutely refused to work with. The first were doctors ( they don't think anyone's time is valuable other than theirs) the second was airline pilots ( they absolutely think they know everything, I know that confidence is important to a pilot but come on...)
And the last and this is written in granite are lawyers, they always and I do mean always try to cheat you.
Lowest form of life on earth, there's a reason so many politicians are lawyers.
