Not sure how to answer your question. If by "price discovery" you mean assigning prices in sats, then, no. Don't we wish we could assign prices! 😀 If by price discovery you mean buying and selling things, or not, then, yes. Maybe you're suggesting talking about prices to try and figure out what's a price you'd pay for items and a price you say, "Nope, too much." Still, the transactions in the market establish prices regardless of our preferences.
