Its actually pretty simple, the same blanket rules which most governments try to push doesnt work, just for a simple fact, that the diversity of environments and needs coming from that cant be captured and decided by centralized point of control. Lets just take guns - most city ppl try to ban them and reduce, because in crowded environments, even if a cop trying to stop someone, he can often put others in to danger just due to how crowded those places are. But on the other hand, if you live on a remote location, where all kind of wild life threatens you, and any help hour away, not having a gun is basically a death sentence. Yet, governments trying to push a blanket policy for both - and that simply shows how ignorant that centralization can become. And this is true in basically all aspects of life, which more and more the government try to regulate.

There can be some level of centralized coordination, but it always have to be tied to the needs of those smaller local units and they have to have the last say in it and it must be a hierarchy of this control coming from the bottom...
