Bitcoin cannot be screwed with in such a way.
Of course it can.
i don't see how people don't discuss this more. it seems to be a fatal flaw in the whole system.
people talk about how the guy who wrote all this stuff solved all problems with it but he didn't.
It is a problem in fact. The only way bitcoin can survive in the long term, is with governments or powerful organizations protecting it. We should wake up to that reality.
This, of course is not an impossibility. In fact I see many governments allready supporting bitcoin indirectly.
