Yes I suppose it would also be usefull to have a friend with a lot of fiat cash, you send them crypto and they give you paper. That way no exchanges and no banks as such. Just an honerable friend that doesnt wish to make a profit from you. 😎

You don't need to have one friend to have a lot of fiat to exchange.
It's stronger to have a community to work together.
You can read the other replies of @dses to have a better picture of it.
Be there for one another is the key.
Peace out.
