The statistic you're poo-pooing puts error bars that are a factor of 2× in either direction. Tolerating that degree of error bar isn't all that difficult, and if you bothered to continue to read the article, you'd discover that the author themself discusses possible error bars, and deflates the estimated operational cost of bitcoin miners by half anyways. And, FWIW, the kind of methodology that was used to produce the Bitcoin energy consumption is the same kind of methodology that is used to produce statistics like GDP, inflation, employment--basically every macroeconomic indicator. If you're going to complain that you can't quantify Bitcoin's energy consumption, then to be intellectually honest, you need to complain that the true inflation rate or the true size of any country's economy is impossible to quantify as well.
