In a homebrew setting would it be bad practice to have no need for money?

So I'm a newer DM and im working on a homebrew setting and in the part of the world the adventure would be taking place is completely isolated continent and there would be very few settlements and the few that do exist are mostly made up of old adventurers working together as more of a nomadic tribe situation so I imagine they would have no use of money instead relying on barter and what not. should I scrap this and just use money or is this fine?
