It seems that way, but there's still the uncertainty always. I don't think "they" will/can shut down bitcoin, but there could be a black swan of some kind. But I do like Saylor's analysis that once there is a 'protocol', a dominant system like Bitcoin (Saylor thinks in history of technology terms, like once the railroad track dimensions were created and implementation spread, it has a huge implied inertia/resistance to modification), the same protocol continues.
