> Non-technology attacks are simply much more powerful. E.g. "Anyone caught using Bitcoin will be executed on the spot by large caliber fire from attack helicopters flying far enough away that you can't see or hear them targeting you", and suddenly Bitcoin is only some obscure and irrelevant thing That's still a technology problem. Make the use of it undetectable. A sufficiently technology savvy Bitcoiner would just wrap his stuff with some encryption and with minimal hassle, you would need to be much faster and harsher to stop them. Besides, if we're assuming civilian execution without trial, then we're not talking about the modern major states. Not a single of the major states could even remotely do such a thing without consequences. The harshest punishments for comparable offences would be for the distribution and possession of child pornography and that is not stopping the offenders, on the contrary.
