With DROs, communities can be formed in which guns are either permitted, or not permitted. Marijuana can be approved or forbidden. Half your income can be deducted for various social schemes, or you can keep it all for yourself. Sunday shopping can be allowed, or disallowed. It is completely up to the individual to choose what kind of society he or she wants to live in. The ownership of property in such communities is conditional on following certain rules, and if those rules prove onerous or unpleasant, the owner can sell and move at any time. Another plus is that all these "societies" exist as little laboratories, and can prove or disprove various theories about gun ownership, drug legalization and so on, thus contributing to people's knowledge about the best rules for communities. (From "Practical Anarchy")
These communities (guns banned, Marijuana banned, etc.) can presumably only be formed if a property owner builds a community and sells or leases land only with a contract to not own guns, not shop/sell goods on Sunday, etc. Presumably violation is handled by appropriate DROs like any contractual violation; effectively, the violator is fined, has to undo the act, may have to leave the community, rates will go up, etc.
Is it considered legitimate in a stateless society to sell property with a perpetual contract (i.e., property cannot be resold without the same contract)? It would seem so; it's just another contract; on the other hand, can one truly be considered to own something so encumbered? Regardless, while that's an interesting side point it can be gotten around by having the owner lease/rent property rather than selling it outright.
Can't the state be considered as one big DRO? Certainly there is not an unbroken chain of voluntary property transfer to it, but there is a reasonable chain of ownership by exploration, voting in a state, and ceding power and land to a central government (e.g., the 13 colonies' ceding of westward land claims for the formation of new states). Unless at the time a stateless society is formed, all property becomes "up for grabs", it's reasonable for property to stay owned by whoever owned it in the previous system. So the previous political leaders could form a DRO, possibly providing increased legitimacy by handing out stock to the taxpayers.
Then this "state DRO" may, like the DRO described in the quoted passage, own land and establish rules by which it is rented or "sold". It could decide that, for example, it will let anyone living within its borders have a vote to control how it is governed. It can tax. It can appoint people to positions of authority, establish police, etc.; in short, since it is now a private property owner - a landlord - and not "the state", it may do all these things as owner that it could not do before, and people must agree to them to buy or lease property within said state. Any violence committed has been agreed to by contract or would be in response to what would now be property crime (e.g., speeding laws).
I don't like this result, but it appears to be a natural result of the ability to encumber property ownership. Then as now, you can move elsewhere: but if every former regional government turns itself into a DRO, then it's hard to move out of the reach of onerous rules entirely equivalent to today (punishment for victimless "crimes", taxation, etc.).
