Nothing we haven't heard 100 times before already.  As usual, it completely disregards the environmental impact of fiat as if that wasn't worth considering.  Where's the "conflict" for all the electricity consumed by banks, card providers, automated clearing houses, ATMs, etc?  Where's the condemnation of the fossil fuels burned when physical supplies of national currencies are transported by armoured van/truck?  What about the metals that have to be mined out of the earth in order to produce physical coins?  Stop pretending that everything else is fine and that only Bitcoin has environmental concerns.
