People taking an overseas vacation use energy. Whether it's an energy waste is your subjective judgement that that activity lacks sufficient utility to justify that energy usage. The people taking those trips probably beg to differ on that point.
Oh, you've taken on less work hours to enjoy your life? Maybe others are able to view that as a waste. Quit stretching things so much that you paint __everyone else__ as a threat or enemy.
I didn't say I didn't waste energy, I didn't say I was an angel, I was merely pointing out the fact that two wrongs don't make a right. "It's ok for bitcoin to waste electricity because people flying internationally waste electricity too" is a pretty weak argument.
Call it waste or whatever else you want to, the fact is, crypto currency uses a ton of electricity that wouldn't be used otherwise. Sure you can go on weird tangents if you want but it is a simple fact that seems silly to ignore.
