This is kind of goalpost moving. It's fair to ask about the human costs of other monetary systems, but I thought we were just trying to determine whether or not Bitcoin was efficient. It's not. But whatever, I'll follow that goalpost for a little while.
In isolation I do think that criticism of government policy to value/devalue and secure traditional currencies would be a good argument... if Bitcoin was well positioned to be a replacement for traditional currency.
But by your own admission Bitcoin isn't primarily a system for transactions, it's a system for storing value (actually I would argue it's primarily a speculative asset, not a traditional value store, but whatever, it doesn't matter). Bitcoin is not in its current state trying to replace dollars, because dollars need to be good at transactions, and Bitcoin is bad at transactions: it's wildly inefficient and environmentally unfriendly, it's slow and has high fees, it requires you to essentially move off chain to get anything approaching a normal transaction experience.
> Isn’t it curious that so little attention is focused on reducing the military’s dependence on fossil fuels?
If the biggest problem with the US military complex was its environmental cost, I would sleep better at night. I think a big reason why people don't talk a lot about how much carbon the military emits is because they're too busy talking about the massive human cost.
But this is kind of silly; a lot of Bitcoin's critics do criticize the military. I'm not here as part of a conspiracy to prop up government invasions of other countries, I just think your "currency" is bad and has fundamental flaws.
> Will you stay silent on the subject now that you are aware of the fully-loaded costs of supporting the USD as the world’s reserve currency?
Bitcoin is not going to replace USD. It's technologically incapable of doing that; it only supports 7 transactions per second and the last time anybody tried to fix that problem, the community hard-forked and had a giant schism. Because of course they did, Bitcoin isn't optimizing for transaction speed or transaction fees and most of the community doesn't care about any of the high-minded goals that Bitcoin was originally sold on. They just want an asset that goes up in value, so eventually they can convert it back into USD.
This could be a longer conversation, but while Bitcoin was originally based around some ideals like democratic access to currency and reduction of reliance on military/global power, I feel like it's kind of silly now that we can look at how Bitcoin has played out to say that the whole movement is still about raising people up and democratizing finance. Bitcoin is primarily a speculative market, it's not driven by ideals at this point.
Also just as a sidenote, but even in a world without traditional finance, most countries would still probably have a military; so even just the core idea of "tanks use too much power" is a little weird to me given that the US is not going to throw away all of its tanks if it transitions off of USD. Bitcoin does not get rid of the concept of exploitation, the US can still steal another country's oil and then sell it for Bitcoin.
> Bitcoin uses less energy than the world’s hair dryers
Not sure if you intended this to sound like a small amount of power, but that is a heckin large amount of power in order to secure such a small proportion of the world's wealth that it has next to no impact on the current exploitative measures taken to secure other existing currencies.
Bitcoin does not do enough to address the exploitative nature and human cost of securities like gold in order to justify its enormous energy expenditure, and there is little reason to believe that it is capable of scaling to the point where it could address those problems, and there is a ton of reason to believe that if it did manage to scale to that point it would in the process start consuming even more energy.
Even taking everything you've said at face value and assuming that Bitcoin is actually just straight-up liberating value from a highly exploitative system (rather than in more than a few ways participating in that same system) -- no; quite frankly, it is not worth using the same amount of energy as Sweden just to liberate a measly 3% of the world's wealth. That is too inefficient, it costs way too much power to do way too little. Come up with a more efficient way to secure that wealth, preferably one that actually scales.
