I don't see many experimentation going on in the "modern" world regarding governance. Without deviating from safe norms and risking failure, we cannot hope to build better systems. Traditions and longevity can only showcase what can survive. We can improve upon even the things that are not broken. The negative is the risk of things going bad.
As you can see, Orania is a small voluntary project that has created and extremely safe, lively community in a country facing extreme levels of crime and violence. Voluntary and small is exactly how this type of political experimentation should be done. The Wild West and the USA that eventually came to be are bold political experiments that worked to improve governance and build prosperity unlike anything that was seen at the time.
