After Stross' "kicking the hornets nest" of Bitcoin, as you playfully put it - he can forget any support of his works. It would be like Asimov declaring: "Robots? Robots are idiotic, I just wrote the stories for a check."
SciFi is about looking ahead, not burying your head in the sand if you don't understand something. The future is here, even if Stross can't quite see past his biases to do so.
