"Talking about" is relatively easy for all four; but IMO the use of accountants and lawsuits is much more likely than people using Bitcoin and JavaScript.
If we don't have lawsuits, there's no process by which someone's failure to have an accountant could be held against them. If you don't have something accountant-shaped that can examine the real world, then you have no way to audit that your debit of 100 Martian Pesos was balanced with a credit of 100 traditional Martian didgeridoos, no matter if the Martian Peso was a cryptocurrency, a fiat currency, or commodity money consisting of transmuted post-transuranic-island-of-stability-metal. If you don't care about that, you're probably only playing with money and assets anyway and are functionally post-scarcity.
We might be post-scarcity, annihilated, or post-apocalyptic in 100 years, but none of these three would likely keep Bitcoin, and only one JavaScript.
