Commerce in space will be driven by the demands of exchange and the economic factors involved.
Raw Materials:
Air and water are likely to be in high demand and even if they become somewhat abundant, will always remain treasured for their inherent importance. Food will be mostly manufactured locally, assuming you have the raw [...]

We know that it is possible to transmit and receive energy via electromagnetic radiation with no wires. The problem is refining the technique to make it safe and make it work beyond short distances. It should be possible with current technology to make charging points in a working (or living) environment that allow [...]

Very light, very thin batteries can now be printed onto flexible substrates.
Cutting-edge printable battery is revolutionizing the field - [nanowerk.com]
For a long time, batteries were bulky and heavy. Now, a new cutting-edge battery is revolutionizing the field. It is thinner than a millimeter, lighter than a gram, and can be produced cost-effectively through a printing [...]

Before attempting to predict how commerce will occur in space or how government will be designed to regulate it, it is important to understand how the basic economic factors will be changed.
