Every major government already has "kill switches" for the public internet within their territory established in the name of emergency planning.  In addition, it is hard to believe that SHA-256 is not completely compromised in all respects by at least one three letter agency -- that could poison the system at any time they chose.  It's important to remember that while BTC may be incredibly useful and has/may continue to provide amazing returns -- its durability in the case of emergency or geopolitical turmoil is open to question.  I don't think OP was trolling.

That said, go BTC go!
