> How is comparing Bitcoin's energy usage with other endeavors an "order of magnitude fallacy"?
The "other endeavors" category above was "digital endeavours" and specifically "Bitcoin versus Facebook", which is an order of magnitude difference.
You've introduced an entirely different category from the above discussion. It's maybe an interesting category [1] to discuss elsewhere, but is off topic from the fallacy we were discussing. Thanks for the non-sequitur, though.
[1] Personally, I'm not so sure it's a useful counter-comparison to Bitcoin: Gold is used in electronics and other industrial needs, beyond its service as a value store/commodity of interest to collectors. Gold is also increasingly rarely the "primary" focus of mines. Most of our Gold today comes from Copper mines and very few would argue we are mining Copper as a value store/solely for greed.
