I see the ST future as being similar to virtual online spaces - things like land are still the subject of commerce because they are somewhat limited, and perhaps one of a kind items or those things which people who feel there is some value in ‘real origin’, but generally physical objects are subject only to the laws of creativity - you can easily have whatever you can build on your own or draw from a database, but anything more interesting than that you have to barter for the intellectual labor involved.
