Bitcoin is the world’s first and only immutable record. As long as there is anyone who wants to use this immutable record (and in a civilizational collapse, I suspect most record keeping will go to shit and so it could become even more valuable to people) they will have to pay others to provide the computation and energy to make that record immutable. The only currency that can be used to facilitate this exchange of energy and record-keeping is Bitcoin.

You may say - why will anyone sell their precious energy to to the Bitcoin network when the going gets tough? And the answer is simple - there is stranded energy in the world that has no other value. It would not cost much to tap it, but there is simply no buyer.

Well, now, the Bitcoin network will literally buy any energy from any where in the Universe. This presents a quasi-gold rush for otherwise stranded energy.

In this way, we managed yet another civilizational breakthrough. We didn’t just improve our use of money in every dimension, we also developed immutable record keeping and incentivized the development of any and all energy sources in the universe.

As long as there is demand for an immutable record, and as long as there is stranded energy that can’t be sold for other uses, there will be a market for the exchange of these two things.

And as long as the token of that exchange is a Bitcoin, a Bitcoin will have relative value to the rest of the physical universe.

Government money has absolutely no bearing on the equation.
