The NYT analysis seems pretty much correct, but the ultimate blame rests with governments who inflated their own currencies.
Economists sometimes say that fiat currency (i.e. currency not backed by any commodity) is superior to a gold standard because it has reduced resource costs. A gold standard requires mining gold, and some of the gold must be used for money instead of for other purposes, such as jewelry and electrical contacts. Using fiat currency allows all that gold to be used for other purposes, and the cost of money is reduced to the cost of paper and ink.
The problem is that fiat currency is inflationary. Not only that,
but as Lawrence White has shown, more gold is being hoarded today as a hedge against inflation than was ever stored in bank vaults during the gold standard. This is demonstrated by the fact that the real (inflation-adjusted) price of gold today is higher than it was under the gold standard. In other words, the resource cost of fiat currency - measured in gold - is actually higher today than it was under a gold standard.
I would say that the electricity costs of cryptocurrencies should be added to the ledger as another cost of fiat currency. The fear of inflation has not only driven people into hoarding gold - which subtracts from the gold available for other consumptive and industrial purposes - but it has also driven people into consuming massive quantities of electricity.
Any useless waste of electricity should be ultimately blamed on governments which abused their monopoly on money to engage in inflationary finance.
If we are concerned about the electricity costs of cryptocurrency, then the solution is to privatize currency so that governments can no longer inflate. Milton Friedman proposed one feasible means of doing this: first, freeze the monetary base by prohibiting the government (and their subordinates, the central banks with government charters) from ever issuing any more currency, ever again. Second, permit private banks and financial institutions to issue their own private currency that may or may not be backed by the fixed-supply public currency. The private currency will have no legal tender law; any individual will be free to accept or reject any private currency which is offered them. Only the public currency will be a legal tender, but its supply will be frozen and fixed. Changes in the supply of money will be accommodated by changes in the supply of competitive private currencies.
Indeed, we have a historical precedent for Friedman's proposal: for most of US history, the only legal money was gold and silver coins. But for daily transactions, most people used private banknotes, not gold and silver coins. The banknotes - which were issued by private banks and had no legal tender - were essentially warehouse receipts for gold and silver that the bank stored in its vaults. And competition among banks ensured that only trustworthy banks survived, so most private banknotes traded at par, i.e. without any discount below its face value. For most Americans, a private banknote saying "1 dollar" was as good as a 1 dollar gold coin.
