From what ive read the plan is to keep crafting a gold sink so having that be the base for exchanging gold between people, that would effectivley make a little money get removed for everything somone sells to somone else thats crafted. Crafting specialization will make it easier to target specific consumersand i deffinately notice things wearing out faster. You dont need thousands of people to have a player economy but you do need desired goods that get removed and need to be repurchased. I buy my gear when i need it if i can find it, and i always buy food and potions. Food and potions are the only crafted goods people need regularly, and how many people arent crafting them themselves?
