So to play devil's advocate, let me ask you a counter question:
Does the price not moving up from here (but stays the same relative to inflation) somehow violate the principles, tenants, or intended usage of bitcoin?
Another question:
How much of that current transaction volume is NOT traders trading to make a fiat profit? Hmmm? 2-3%, maybe?
It doesn't matter what the purpose and intent of any part of the current transaction volume is. Especially when nobody can prove claims of that sort one way or another. Everyone pays their fees. And that's another thing that needs to be considered, bitcoin absolutely must be able to resist "spam attacks" or whatever jargon people cook up next time it happens. Otherwise it is simply not good enough for mass adoption.
And you did not answer the question.
