Voluntary action and overcoming coordination problems don't mix well. Best case is the volunteers overpay tremendously for things that benefit a ton of free-riders (those who benefit, and could pay, but choose not to). Worst case it all falls apart and we invent government to compel cooperation and then crush/conquer any societies that don't follow suit and remain awful, disorganized messes.
