I don't really understand this comment? Claiming systems or building districts should cost unity?
Yeah. If everything costs a bit of both, there is only so much you can do at any given time, and we have a better mechanic to reflect the administrative/bureocratic effort demanded by.... well, anything really.
Assume everything that consumes unity (such as traditions) and influence (such as outposts) remain as they are. But districts require 1 influence and 1 unity. Buildings too. Capital building upgrades costs 50 of each. Starbase upgrades 75 of each. Or some other ammount.
You would be caught thinking all the time if it is time to expand or consolidate, go tall or go wide, invest in the military or in pruduction, specialize what you have or go building outposts all over.... since you have a limited amount of administrative effort accumulated. You know? STRATEGY, of which this game is so painfully lacking except foe going all in, all over the place. As things stand people just have the "choice" of maxing everything out: fleet capacity, jobs, pops, extraction....
