Well you can't realy judge it like that. The Houses have indies that fly Capships too, so at least there is something to shoot at. Also the Coalition by itself is a remnant of an own House, let alone a whole Union, maybe it's smaller now but it carries on the spirit of a Government.
So I think why not allow it to indies, as I said limitting them to maybe Omegas only or at some point even allow them expand into Rheinland and Bretonia, if they're behaving well. So just asking about the Typhoon, the Carrier is a special perk for the official faction.
I mean seriously like I said maybe either that line which defines that they can help civilians or giving them access to Typhoons so they can at least reasonably hit the Law Enforcement (Bretonia and Rheinland) instead of just limited to Gunboats.
So yeah, either that line getting changed or something or the way it would make sense would be letting them use a Typhoon. I mean I'm not even saying "Cruisers" just add "and Typhoon". If you're limited to engage only Law enforcement, militaries then seriously let them have the Typhoon so it somewhat motivates someone to at least fly on a Coalition ID even. With its current form, many get bored quite quickly because of how limited it is.
