Lol, no, not discuss: elaborate
I understand what you are pointing at. Sovereignty is a bit of a problematic concept though. Has been discussed by wise men with respectable beards since the dawn of times and they still do not agree.
You could define a DAC as a co-op that by definition, autonomously, acts in the best interest of its owners.
For as far as I understood it, the 'autonomous' in DAC serves a double purpose. It expresses the limits to the the extent in which external forces can influence the Company, but it also expresses the limits to the extent in which the owners (internal forces) can influence the Company.
If you use sovereign in the sense that the owners cannot influence the 'organization or business' this is not correct. If you use sovereign in the sense that forces apart from the aforementioned owners cannot influence the 'organization or business' ; might as well stick with 'autonomous'
The limit in which the 'internal forces' can control the company is what is of value in a DAC. Mondragon, 'the Miracle of Basque Country' (or the ONLY business that seemed to have survived the crisis in Spain without a scratch), went bust because the internal forces were allowed to exert too much control over it.
I hope I'm making sense here.
