I just don't understand why people can't be honest and say "this is great for mail order drugs, guns and kiddie porn, which I enjoy." I really do hate cryptocurremcies because of their ludicrous waste of fossil fuels, and because so many arguments smell of the above.

It'll never be economical to mine cryptos with fossil fuels in the long term. Commercial mining will end up concentrated in Iceland etc. where the electricity is both cheap and difficult to export.
Short term, yes, unfortunately they're using fossil fuels but only because of Chinese capital controls that effectively subsidize Chinese miners.
