I don’t agree.The Imperium isn't claiming the asteroids and stuff. They are asserting Imperial law in that area. The national government in the US regulates interstate trade, requires states to accept documents from other states, manages some land, and so on. Both the Imperial Navy and the Glisten Planetary Defense forces are going to patrol Glisten space. Glisten governs the system. But, whereas the Glisten government is largely able to do whatever it wants in Glissten City, it is NOT free to do whatever it wants in space. Does the government of Glissten control the mining rights to the asteroids? Yes. Can they impose a tax on all shipping passing through the system and using the starport? NO.
Are you destined for the Imperial pokey instead of the Glisten jail if you do crimes in space? Yes. Can the Glisten planetary navy arrest you for those crimes? Yes. Can they tell the Imperial Navy not to arrest you? Nope. Can they arrest you for some Glissten government crime if you are on your ship? Probably not, unless the Imperial authorities approve it. Just like Texas Rangers can't arrest you in CA for crimes committed in Texas. They have to ask CA to arrest you and extradite you. Which CA might or might not do, depending on how dumb the law you are trying to enforce is.
It is going to be a patchwork of overlapping authorities with the balance depending on the strength of the government on that planet. And more complicated than is likely ever going to be worth dealing with in any detail.
Glissten could impose a tax on shipping using the starport. That is how starports gain revenue.
This analogy is flawed.
For IRL examples:
For vessels in international waters, no nation holds sovereignty over the seas. Rather, the laws of the country where the ship is registered would apply. So, if the ship is registered to the United Kingdom, then the laws of the U.K. would apply.
In space, while the Imperium has sovereignty within their borders, it is highly likely that the laws of the system where the vessel is registered also has applicability.
If you jump in system with a load of nuclear torpedos, even with an imperial permit, I am sure that the system government would want to make sure that you aren’t going to use them in-system, or sell your cargo of weapons to the insurrectionist.
