It is absolutely not
"It is like trying to ban the internet because it takes up 70 percent of phone line bandwidth."
The phone line takes a ridiculously small amount of energy compared to the amount of data being transferred. This is a strawman argument without any basis in reality, but I expect no less from someone purporting to defend the best method criminals have to whitewash their ill-gotten gains.
Banning crypto would put paid to many, many pyramid schemes and other scammer attemps to make an easy buck. I'm not saying crypto is only used by criminals, but when criminals have massively adopted something and use it so successfully, there might be a good reason to put a serious crimp on it.
