Bringing land ownership into trade changes things considerably, in my opinion.
The trade of which you speak brought to my mind an image of a post crusade english market... existing after the crusades yet before the Lords of the Land stepped in and outlawed all transaction tokens but their own.
In the new markets of post crusade england a boot maker might give a boot chit to the miller for flour who might then give it to a guild member he wants to do work on their mill. The peasants were accumulating wealth and with such trade; as you rightly mention; more freedom. They still did not own land at this point.
By adopting crapitalism volunterists are destined to create a new boss from the old one; should they ever move from theory to becoming actualized, in my opinion.
Please see my other comment regarding the objective necessity of a universalizable property norm if violent conflict is to be minimized.
