I dunno how much she's worth now but Gina Rinehart used to be worth $20b.
How much physical money you reckon she has?
You're being precious, Leo. Whether that money is folding plastic, cold gold, or spinning electrons is immaterial (unintended pun), and if you just dumped a sufficient quantity of any of those forms on the market out of nowhere you can sink it badly enough to need an extended period of recovery. Kinda like water, it's necessary to life (economic, in this case), but dumping 20b litres (dollars) in one place without prepared drainage is going to fuck shit up for a while.
And you are partially correct, in that money is always being created, but that is not worth. A can of coke was not worth less in 1950 than now - but it cost a helluva lot less. That's inflation, and it's caused by money being created. In the above example, you drop $20b in the local economy and prices across the board will go through the roof (at least until the flood waters have drained) because everyone and their dog has $100 notes to blow their nose on and the worth of things has to hurt pretty much the same.
