What the author fails to address is the most recent research into the planned economy that Towards a New Socialism advocates. It advocates for an economy that is still socialist in nature (in seeking to eradicate the commodity form) while still aggregating opinion into production as market forces do. This is accomplished by using a labor token while using market forces to influence prices and planning. Sure, it can't be optimised perfectly, but neither can our current one, and that is never the goal of a socialist economy anyways.
