I'd be interested in your counters to his arguments.
I think his arguments spring almost entirely from his fear-mongering hyperbole,
It's a scam!, but I'll kick it around a bit.
First, to your point that it's worthless in SHTF, I get that. And that's a reason I've put some faith in physical metals. But, it's not any more "worthless" post SHTF than pre-SHTF...it's just harder to access (theoretically, because if the S hits the F, it hits the internet also) and/or exchange for other value. But, also theoretically, I can carry a lot more crypto "wealth" on a thumb drive in my pocket than I can 1oz gold coins.
But to his main points, he says it's useless as a means of payment and they're "accepted almost nowhere", which is just untrue. Unless they've changed policy very recently, both Apmex and JM Bullion will send you any of their products for your bitcoin, and they'll DISCOUNT their product compared to their credit card purchase rate. Gold, silver, platinum...
As a "store of value", yes there's volatility. But, it's value on the market has continually nudged upward. Unlike our "stable" USD currency which has trended consistently downward. And "cryptocurrency trading exchanges" are NOT storehouses as he'd have you believe. Part of crypto's value, and specifically its preferred value, is that there isn't a central authority controlling it.
His "thing itself" point only has merit because there IS such a thing as a paper (cloth) dollar. But, there are maneuverings afoot to phase cash out of existence, also. Same with those others he cited as "better stores of value and things in themselves": pounds, euros, yen, renminbi. I believe I read somewhere that actual physical cash is a drop in the ocean of ones and zeros otherwise stored in bank accounts.
I try to shy away from the ad hominem dismissal of someone's thoughts, and give them the benefit of the doubt, generally. This guy has an agenda to keep his fiat scheme propped up, so his rhetoric should be met with a healthy dose of skepticism. But, I think he's just a BS artist con man. Actually, reading what corporate shills like him have to say about crypto makes me want some even more. Got any to sell?
