So a bit about the NUN...

The UNG (United Nations Government) became the NUNG (New United Nations Government) following events of Macross VFX-2. This was a logical course, for the logistical nightmare posed to an ever expanding UNG meant it was difficult for a centralized government to tackle every problem in the galaxy. Never mind trying to enforce central authority over the overwhelming Zentradi population was impossible from the get-go. They still outnumber humanity today, and unlike the latter, every space-borne Zentradi is a warrior. The Zentradi today functions as allies to the NUN, and the keyword here is 'allies'.

If we are to draw a historical analogy to the NUN post VFX-2, it would be akin to the visions of the founders of early United States, where states are sovereign entities, but a central government is still responsible for conducting foreign policy, taxation and raise a military in case of war. This is the system of the NUN. Planets & colonies are sovereign, but the NUN regulates taxation, interstellar travel, provides defense, setup HQs and install attaches. The NUN is also responsible for representing member states in foreign policy and settling disputes. Moreover, as a general rule, the NUN do not interfere with the domestic policies of sovereign colonial or planetary entities unless they come into conflict with NUN interests. For example, some colonies prohibits full-sized Zentradi, some colonies allow cybernetics, some colonies deem foreign organisms illegal... etc. But orbit and beyond fall under NUN jurisdiction.

Then we also have PMCs (Private Military Corporations). They are not completely independent entities. They are subsidiaries of the NUN and must abide by the latter's authority. When Jeffrey Wilder decided to go full 'pirate' in Frontier, his actions were initially considered treasonous. Corporations such as Chaos can be rented out, but going back to my previous point(s), when interest of Chaos conflict with NUN, the latter takes priority.
