whoa - I certainly don't think that people starve or die of thirst because they are LAZY!
the examples were simply to illustrate that the cash is one of a number of ways to get water, and therefore, I feel, can't be a need in and of itself....
economies collapsing are not just about a lack of ready cash, they are often precipitated by rocketing inflation, critical services failing and infrastructure collapsing, civil war, removal of foreign trade exchanges, and a lack of things to buy with that cash.
I guess I think of it like this - if you air-dropped just cash into a country whose economy had collapsed, would their needs be met? - would everyone be able to eat? I think that they would need food/water/medicines/shelter/sanitation services, not cash - so the cash is not a need.
anyway, I'm sure we can agree to disagree seeing as I have derailed this way off-topic... sorry!
