I am tired of people of coming up with these nonsense comparison. Bitcoin co2 emissions is the same as Hamburg. It uses more electricity than Las vegas etc. Have they accounted for the amount co2 the food that 1.8 million people in hamburg consume.
I think the underlying assumption in those comparisons is that Bitcoin is essentially useless.
So while Hamburg produces CO2 because of all the people and economic activity going there, Bitcoin produces the same amount for no actual benefits. In that case the comparison does illustrate the amount of waste.
Now, on the other hand if you're of the opinion that Bitcoin is something of value that makes a positive difference and produces something useful then the comparison does look random and nonsensical.
