Not really - Bitcoin Cash is an entirely different "currency", that shares the history of Bitcoin up to the point where it forked.

I seriously doubt it. $10k / week for Jack Dorsey is a reasonable amount to use as a hedge against Bitcoin going exponential again. If it does, he's even richer. If it doesn't? Meh, so what. It's "only" $520k / year, and it's unlikely to lose all of its value anyhow.
If the US made dollarsPlus and gave you one for every dollar you currently have and said you can spend them just like dollars. That is a different currency and would not be inflationary I suppose.
(b) The effective inflation rate is massively negative because everyone keeps losing their keys. A friend asked me re: Satoshi "If he didn't believe in what he built and the future, why isn't he moving his genesis coins? What kind of man would do that?" My answer was: "the kind of man who lost his keys."
(c) The inflation rate of the crypto space in totality to your point is astronomical, since anyone can just fork a currency, give a few tokens to some promoters/shills/exchanges, get listed, and boom, that's a dump-truck of sweet sweet crypto.
(d) I'd watch the hell out of the Jack Dorsey reality TV series.
You think he is planning on having to leave the country? How would he have time. The average CEO is working 80Hrs per week. Much more than their over paid thralls. He is CEO of 2 companies. That is 160Hrs per week. Plus the 10 day silent meditation retreats. You guys do not realize the excruciating demands placed on todays CEO's. They truly are our modern hero's. He should be given his own reality show.
