Who says a lot of that previous physical world won't return? The Gods of the Copybook Headings and all that?
E.g. how long can the US Federal government continue to borrow "a trillion dollars a year" to fund continuing operations? Not forever, I submit to you.
(And, yes, I know it's dropped to around half of that, but there's no plan to drop it further, and that's not counting things like the Fed keeping interest rates so low.)
Couldn't agree with this more. It's going to be interesting to see how things play out.
