I totally agree, but I'm also curious how expensive in terms of resources distributing paper and metal currency is?

Presumably mining zinc, copper, aluminum, etc must have pretty big costs to the environment? Paper is mostly paper but isn't it also some special silk? At least here in the US.

Those seem slightly more renewable for paper. But yea, creating an extra power plants worth of fumes is pretty shitty over time.

I believe there's one currency which at the very least does some sorts of scientific calculations with the processing power? Maybe we should at least encourage those types of coins.
