I think it's more that you need layers. A centrally planned layer of regulation and safety nets that provide a base level to keep things running (and people alive), but without the cost and inefficiency of trying to control everything, and then a more efficient, free market–like layer on top that relies on the lower layer to provide the "free" in "free market". I believe it would be more productive to argue about where the layer boundaries should be, rather than endlessly arguing about whether one or the other layer should even exist. (Because they'll both always exist. People will help each other out even in a free-for-all; and black markets will always come into existence in rigid, fully-planned economies.)
