For what it is worth, and, for a moment, taking this at face value, does this not begin to make an argument for some cryptocurrency taxation to cover infrastructure investment and costs to support the transactions?
The “holy grail” of currency exchange will be burdened with unfunded overhead as it becomes main stream?
At first I thought it was preposterous that cryptocurrency could use much power - after all, what could a single transaction cost on your computer/phone and the back-end server. Then I learned every transaction is spread across MILLIONS of servers and the energy consumption is becoming very serious. This cost must somehow be built into the cost of the currency just the way the cost of printing paper currency and minting coins is built into those currencies (except those costs find their way back to us in our taxes).
