Not just small sovereign collectives, but any collective (including the government). The key is for the collective, overall, to sustain the rights of any entity that is a part of it. That means sovereignty for all organizations, and sovereignty for each individual. But, that sovereignty ends at the boundary of another sovereign entity.

This isn’t just s system of governance, it’s a system of morality as well. You can do anything you want, but once it starts impacting others, you begin losing rights. Effectively, if you cannot come to an explicit consensus, implicit consensus is permitted. There are notable grey areas - and since consensus cannot be achieved there, they should be left to social involvement, or to diversity, to handle.

In history, the most egregious actions are those where collectives impose upon individual will, and vice versa. Establishing sovereignty rights is a moral foundation that can, to significant degree, mitigate that.
