> Nationalism is a Bad Thing in my view.

First of all, nationalism is not national sovereignty.

The former is a social construct which an individual embraces while the latter is a principal of law which a group embraces.

The former is hardly useful, but the latter is vital to all existing nations. No nation is going to willingly give up its right to self governance.

> I'm in favor of putting limits on concentrations of sovereignty.

So, essentially, you wish to live in a world without borders where one or more unions govern many places regardless of geographical separation?

Because that worked out so well in the past...

Essentially, yes I do and I'm fully aware of the operational and philosophical difficulties of such an undertaking. I have ideas about how to implement a distributed governance approach without falling back into patterns of autocratic central control, but am still working on how to make those robust against attempts at hijacking and so forth.
