The tl;dr amounts to:
* author agrees with Stross that bitcoin is energy intensive.
* author says there have been improvements to carbon footprint (as if that some how address the issue of theft of other people's electricity/CPU cycles being more efficient than spending your own electricity)
* An argument about deflation that amounts to "there's no consensus in economics so it's fine if we run speculative experiments with economies"
* A non-argument assertion that bitcoin is somehow no worse than cash as a vehicle for illegal/unethical behavior.
Somehow this is suppose to amount to a take down of a dude who wrote literally an entire book about how algorithmically mediated systems which do not depend on human judgement are inherently inhuman and unconcerned about human ethical concerns.
"It’s hard to believe that an author who wrote about algorithmically run 2.0 economies and trading exchanges for personal reputations can fail to see the precursors of that tech in the real world."
wat.
Seems like the author seems to be the primary source of misunderstanding.
