Cryptoanarchism in nature

Indigenous myths describing a feathered or rainbow serpent appear to relate to the Milky-Way's appearance from earth.  Indigenous peoples are generally excellent stewards of nature so I respect their right to autonomous zones covered by Native Title. As part of the six-years-at-full-warp push to cypherpunk 2027 I propose the world move from freehold to leasehold and Native title exclusively. That is all private land be phased out over 99 years.  Also we may then move to ' Rainbow Serpent ' time with our galaxies rotation providing the calendar instead of some myth from the Middle East.
