A good reason like profligate waste of electricity? Like using so much power that it's in a race with the Internet itself?
It's pretty ******* telling that you fail to address this every time it's brought up. One might suspect that it's because there is no reasonable answer to it. Each mined Bitcoin uses as much electricity as, what, 2-4 US households would use in a year?
But, sure, let's just keep going. What's the point of a death spiral if there aren't scumbags profiting along the way?
Waste not want not. 1 ounce of Gold reportedly requires 8.3 Terajoules of energy to mine. As of now that's $1,841 USD worth of Gold.
Let's convert 8.3 Terajoules into Kilowatt Hours:
Where 1 Terajoule is equal to 277,778 KWH,
8.3 Terajoules = 2,305,557 KWH
2,305,557 KWH to mine $1,841 USD worth of Gold. (Two million three hundred five thousand five hundred fifty-seven KWH.)
How many KWH to mine 1 Bitcoin? Reportedly it takes an average of 143,000 KWH to mine 1 Bitcoin. (One hundred and forty-three thousand KWH.)

Bitcoin is at this moment is valued at $17,820 USD per Bitcoin.
What's worse for the environment mining Gold or mining Bitcoin? If one Bitcoin is worth approximately 10 ounces of Gold, let do the math.
10 ounces of Gold at 2,305,557 KWH per ounce to mine = 23,055,570 KWH (Twenty-three million, fifty-five thousand, five hundred seventy KWH.)
Gold requires 23,055,570 KWH and approximately the same value amount in Bitcoin requires 143,000 KWH.
Gold is MUCH worse for the environment as it requires exponentially more energy to produce than Bitcoin. Let's get rid of that nasty Environment killing Gold.
