As all the slogans, "everyone buy bitcoin at the price they merit" cant represent an absolute truth, but a large approximation and euristic.
I like a lot this slogan because I find that its a good approximation (correct in most of the cases) AND its also a lot controversial. Most people dont accept it and, applying some game theory, they have all the (communist) reasons to affirm that its just false.
Its not perfectly correct, but after all the complains, its mostly correct. Even if it hurts.
