I think military determinism is a good analogy for monetary determinism, but I don't agree that you've understood monetary determinism.
With electronic exchange, we can use anything as a unit of account and claims on that anything as a medium of exchange. There's no reason we couldn't resolve electronic transactions in oil futures, or Bitcoin ETFs, or Bitcoin, or Gold ETFs, or AAPL shares. Those all work perfectly well as digital instruments. They're all countable and have a fiat price.
In a world of efficient electronic transactions and trustworthy digital claims on real resources, the question of money comes down (in my view) to durability. If I'm going to hold a physical asset, what rots least? And there the answer is gold, for purely electrochemical reasons.
In a world of inefficient electronic transactions and untrustworthy digital claims on real resources, the question of what to use for electronic transactions comes down (IMO) to trustworthiness. And here Bitcoin is much better than fiat. I've repeatedly observed that Bitcoin looks quite sane when compared to fiat.
I am very much influenced in my thinking on money by the Austrians (especially Menger) and Yarvin (who in economics is a pseudo-Austrian). See: https://www.unqualified-reservations.org/archive/john_law_safehaven Basically, I think Yarvin is right to claim intertemporal difference (the fact that I am given resources by my employer this Friday but I would like to buy chicken tendies next week, or 50 years from now when I retire) as the main driver in the selection of money/currency. Unlike Yarvin I deny the primacy of relative interest rates (because you can borrow any asset and sell it in whatever is the going currency).
I strongly disagree that Bitcoin is inherently deflationary. I think the rate of supply growth is decreasing (well, to the extent that we pretend supply is nonzero). But that's still inflationary. More units are being added to the "money" supply, which is inflating with every block mined. If you're referring instead to the fiat price, keep in mind that the decreasing reward sizes (and lost wallets) reduce the supply of available Bitcoins, not the demand. Price is the product of both.
I think eventually we will either see Bitcoin "mining" become uneconomic and the chain is abandoned, or we will see fiat collapse and in the rubble people will prefer something tangible and indisputably valuable rather than a speculative digital asset.
Also, I'd just like to mention again how much I hate the psyop-ness of all the bitcoin terms. These aren't coins, you're not mining, stop using pictures of gold coins with a B on them, and get off my lawn.
