This is what Chibber calls the "pluralist theory" which he argues is not entirely false but rather incomplete. I hope this will be of interest to you : https://youtu.be/R5R-9X_BtP4
I'd be more interested to hear what a local bartender might have to say about any of this than a marxist scholar. Hard pass. Also, naming a theory does not give it credence. So simply saying that a person said a thing and gave it a name tells me nothing if you don't tell me what they said. Linking to a hour long video is not a good substitution for defining your terms.
Otherwise you have to admit that there are many groups who have many competing points and goals for legal systems.
I thought it was pretty clear that "pluralist theory" was referring to that last bit so I did not feel the need to define but I guess it was not so sorry about that.
The hour long video was for the purpose of investigating further the matter rather than providing a definition.
I do understand that you are wary of scholars, I am myself. A title is not a guarantee of truth and knowledge is valuable when it is the product of good research and good method, something an academic title cannot guarantee alas.
I guess that now I should add that being a barman is how I currently sustain myself while learning to code. :)
