Define property precisely. Define it with respect to:
- Transient physical objects, such as: air, animals, eroding soil, water, root systems, etc.
- Physical extent of property with regard to land (above and below)
The Bill does not define property. Instead, it states that "The procedural rules given here are intended as a starting point for the development of rules for maintaining and enforcing natural rights. These rights do not change, but the procedures for maintaining and enforcing them can be continually improved." If you are interested in theory of property, there are many other discussions which address it.
