I understand your perspective, but disagree.
Central governance is, in some ways, a response to complexity. If you extend the "governing as close to the local level as possible" too far, you risk an unnuanced understanding because the local level can't be an expert on every system they interface with. For example, do you have the knowledge to accurately assess the risk when you take a flight? If you're like most people, you probably don't know enough about aircraft maintenance, or avionics, or pilot training etc. I know libertarians may disagree but don't think a mish-mash of localities helps in this case either, at least not in the short-to-medium term when you risk a lot of bad days before everyone agrees on a set of standards. This is exacerbated because of a lot of cognitive biases regarding how we perceive risk. Particularly with big systems with lots of complicated interfaces, the lowest level of effective governance may start looking an awful lot like a centralized government.
I would argue it could be better improved with fundamentally refocusing politicians attention. When half their time is spent campaigning, it obviously constrains their ability to craft policy.
