Earlier quoted context omitted.
if you want to see it that way, sure, but i'd say it's stretching. airplanes convert energy into miles travelled. bitcoin converts energy into security of an asset. if nobody needs to travel or nobody needs the security - no energy is spent.
Personally I have a problem with how much energy is needed in the conversion in both cases, but my point is that both formulations are sophistically working around the fact that bitcoin and air travel both consume a lot of energy.
You may not like how much energy is spent on maintaining security, but it’s not bitcoin that necessitates it, it’s the market.
Bitcoin opened a Pandora’s box by showing the world how it can be done and now if people say they want an attacker to take 1gigawatt to overtake the network then that’s what will be spent to protect against such attack. With or without bitcoin.
