Unfortunately that can't be the case because of Gresham's law and the fact that sheeple prefer the money with the stamp which is backed by military force, because sheeple want hassle-free money that is enforced by the State. Study 1000s of years of history.³⁸
³⁸ Shelby Moore III. Value of currency has historically been public confidence in it as a reliable unit-of-exchange. Bitcointalk.org, “Precious metals are not useful in a collapse scenario!” thread, post #62, Nov 2, 2016.
The circulating currency unit-of-exchange form of "money" (as differentiated from the Gresham's law hoarded higher quality store-of-value form of "money", e.g. pre-1965 U.S. silver dimes) is always subject to a power-vacuum on who is in control of the legality of legal tender.
Satoshi's PoW (and best-of-breed alternatives thus far such as DPoS) is also a winner-take-all power vacuum.
The world is not going to entrust the control of money to some cartel of mining farms in China, nor the whales who control 80% of the stake (money supply) of Steem(it).
This (along with user issues such as security, ease-of-use, and applicability to mainstream commerce) is why crypto-currency is stagnating. We haven't improved on the problem of money yet. The world will instead rather turn to a political power-sharing monetary reset wherein the IMF SDRs will be valued by weighted basket of national currencies, precious metals, and perhaps some key commodities.
If we are going to offer an alternative to the coming SDRs system (where national currencies will be backed by SDR reserves and all the nation-states will be destroyed by borrowing in SDRs with wages paid in depreciated national currencies, which is what destroyed the PIIGS especially Greece), then we need a crypto-currency that has an equilibrium which isn't a winner-take-all power vacuum disequilibria.
I have a whitepaper coming which proposes a radical new design for crypto-currency which is posited to be a solution. I also propose solutions for the other items holding back crypto-currencies (and blockchains) such as a solution to end exchanges fraud, a solution to eliminate theft of private keys, and a solution to making crypto mainstream (virtual) commerce.
