Ideal
An ideal system of law would:

1. Have as many decisions as possible be made as close as possible to the persons and facts;
2. Maximize transparency of expectations;
3. Minimize the amount of information that is circulated beyond the parties themselves;
4. Allow groups to self-define diversely; and
5. Maximize interoperability.

Some of these are in tension with others, but correct handling of information permits huge gains.
