after the revolution, there will exist a wiki distributed across a mesh network filled with items that people have created designs for, along with their specifications. You'll be able to read other people's comments and modifications and ultimately select the item you want. But it won't be shipped to you across the world; because patents/copyrights won't exist, you will just take the design to your local fab facility and construct it with the help of the people who volunteer there. #thinkingutopia
