What proof do you want? Real currency can be printed on paper or forged into coins, and then used until the physical medium wears out with zero electrical usage and zero transaction fees. No digital currency of any form can beat literally zero.
Everybody keeps every dollar they own physically on them at all times.
These dollars do not have to be printed, the cotton does not have to be woven, the plastic does not have to be stamped, the dyes do not have to be mixed, nobody has to account them, nobody has to account for their storage, nobody is maintaining the number and circulating supply of them, nobody is regulating the distribution and influx through centralized institutions.

Literally zero.

Sounds like a cakewalk.
