from the very few I know, I didn't see governance and law in blockchain projects. What I perceived is a never ending shared network of operations that can basically replace companies.
The conceptual model is of the governance being in the consensus layer, which operates independently of other political systems, and the law being in the programmatic contracts the blockchain executes.
But yes, there are other ways it can be conceived, and yours seems valid.
But I also believe we are very very early, and it will take maybe 30 years to develop to start massively transforming industries.
