No, no, you make a good point.

It's similar to the Bitcoin energy usage argument that nocoiners like to throw at us.

OK, Bitcoin uses energy. What about the legacy system?

How many kiloWatt-hours of electricity and therms of natural gas have been consumed by the legacy banks, ATMs, armored car services, etc.?

Email and internet dealt with the same thing. I bet the energy footprint of the postal system has decreased significantly, offsetting at least some of the energy usage of the internet.
