I think it represents a much more interesting vision of "postcapitalism" than just opening up IP. Renting out excess capacity (in a brewery or other production facility) allows IP-only companies to get into the business. Not only has it allowed Mikkeller (and others, including his estranged twin brother) to get into beer with litte or no capex, it's allowed him to operate on different continents, solving another host of problems for working in a global marketplace.
Apply that model to other industries and there could be a Cambrian explosion in innovation and creativity.
