> Do you have an example of such an alternative way of organizing society? An example that has been tested in a large society?
There are examples of self-organization to various extents, although there is obviously no example of a society exactly like what I propose. Many parts of what we currently consider the standard role of government have been done without government by many societies. What is considered the "standard role of government" changes quickly (it would probably sound ridiculous 200 years ago to say that Western states would tax something like a third of national GDP). Private arbitration is already quite common, and government courts are widely recognized as slow, expensive, and unreliable. International trade by definition has no higher level central body governing it, and that constitutes a decent chunk of global GDP. Decentralized mechanics already govern nearly all everyday transactions which are not worth the cost and unreliability of using government arbitration (restaurants generally try to satisfy their customers not out of fear of prosecution or litigation).
> It's easy to propose theoretical alternatives with no regard for psychological or sociological effects (which are complex and therefore difficult to predict in theory).
In fact, the vast majority of my arguments revolve around psychological and sociological incentives. You're right that any significant change to society is difficult to assert with absolute confidence. But that alone doesn't mean that a given proposal is more like to be bad than good.
> In order to achieve what you want, you need not only a better form of government, you need a way to hack culture to get it to tolerate that form of government without significant shocks to perceived quality of life
I'm a proponent of gradualism, so while that's a valid criticism, I don't think it applies to me.
