In a scenario where the USA puts up a national firewall preventing miners/clients in the USA connecting with miners/clients elsewhere,
The US government would have to go through a considerable legal fight to put such thing in place.
<snip - other interesting observations that I hope people pay attention to.>
The US government would have to go through a considerable legal fight to run a gulag system in which they (or lamentably, 'we') maim various people...including ones who are completely innocent of anything remotely threatening.
Similarly, it would be quite a legal stretch for the US government to have legal justification kill US citizens anywhere on the face of the earth (including within our boarders) and without oversight from the justice department.
Similarly, trolling through vast seas of personal data would be completely antithetical to the fundamentals of our founding principles.
Or, on the other hand, are these things such a stretch after all???
FWIW and on a tangent, I hypothesis that a fair part of the Bill of Rights has actually been nullified by an order which is a state secret about a decade ago and that the action itself is a state secret. This hypothesis can explain a lot of mysterious actions and behaviors and I've yet to be able to invalidate it. Admittedly invalidation is kind of a game/trick like thing due to the 'state secret' aspect, but I assure the reader that this was unintentional in formation of the hypothesis.
