It's possible that confusion and conflict coming from there being two chains (imagine if a user sends bitcoin to a retailer who then claims they never received a payment because they were actually expecting coins on the b2x fork) could depress the price. Now we know that won't happen.

I stand corrected, didn't consider the case of both chains crashing due to the fork.
I don't know, only if they did not understand that it's a win-win-win situation... they would have equal amount of coins on both chains so none of the three possible outcomes would be actually losing.
