Like how we used to have them?
Where there wasn't a market board but instead a sea of retainers and you had to click each one to see what it is selling and there wasn't a way to search for a specific item?

Or do you mean more like the markets people make in their housing since we can set up NPCs in our houses and yards and people can buy directly from their inventories? So people set them up with a theme and load this retainer down with lumber, that one with fashionable clothes, that one with raid food, etc.

OP I'm not entirely sure what you're asking for when you just say "physical markets." Can you elaborate?
