Something I hope Sunward helps flesh out is the political systems of the Inner System. While states and nations are obsolete in EP, legal systems are more important than ever. How are laws actually produced?
Hypercorps need legal spaces in order to function. While a corp could own an entire habitat and run everything in it, this is often uneconomical and it would still need to trade with other corps. This trade requires jointly agreed contracts and ways of enforcing them, usually using trusted third parties. It is not too hard to imagine libertarian/extropian solutions but if that was the case then the inner system would simply be a big bunch of extropians. Clearly they are more statist than that.
It is not implausible that the initial space colonies used a derivative of current maritime law: habitats were registered with a parent nation, and followed its laws. Conflicts were handled by arbitration and international courts. Some corps used "flags of convenience nations" that didn't care to control what they did as long as they paid, others shopped around for nationalities with suitable law and taxation. Some nations were useful as legal forums in space: belonging to them made contracts, enforcement and arbitration easily manageable (and kept legal costs down), so many corps choose them for their legal properties.
The Fall threatened this system. Many nations had effectively ceased to exist, leaving the corps registered there in a legal vacuum. Sure, in the chaos they could do whatever they wanted, but that was bad for business: business thrives when things are predictable, transparent and trust can develop. Declaring their habitats sovereign nations could certainly be done, but meant that now the corp was responsible for running their own legal system - the lack of trusted third parties would hurt it (would anybody try to settle a tort against Cognite in a Cognite-owned court? No, and hence nobody dealing with them would use their legal space) In some cases surviving governments may have been co-opted to create stable nations of convenience.
I think the key to the Planetary Consortium is that it represents an attempt to create something like a sovereign nation with related legal space but without all the baggage of the old nations. It is more like an international organisation than a state, but one of the key functions is to act as a top-level provider of law and legal services. This is why the Morningstar Constellation is such a threat: they might be competing with the Consortium by having a newer and more streamlined legal system, enticing hypercorps to join them. Right now the Consortium has economy of scale, so the Constellation needs to really tempt corps to join their system.
Have I missed something?
