Commercial discussion promotion vs curiosity/interest/consulting others about value.
Just for the sake of freedom of speech, I don’t see any reason to control $$ discussions as long as its not commercial or intentional promoting backed by a hidden interest.
Even Patek is talking $$, do you remember their nautilus ad: “one of the worlds expensive watches is made of steel”.
Another scenario: Imagine the situation that prices are not discussed anywhere! So a Patek enthusiastic will enter a store, pay whatever a greedy dealer will ask for without knowing the real value of the watch.
IMO Price/value discussion is acceptable as long as it is for the sake of knowledge / curiosity / decision-making / consulting and not by any mean commercial.
