i think Dan did a pretty nice job with balancing the game in terms of
Research = the minerals you can get at your rank
In a lay man's term Even if you have very high tech gadgetry. you will not be able to pay for it unless you rank up a bit. get more mining planets and get better minerals as you rank up..
Simply stopping your ranking up will not stop the high upkeep that your ship will need with the high tech research you are having..
Imagine yourself with an upkeep of 1.1 billion per day with the amount of minerals you are receiving and the amount of planets that you have... oh and as the game progresses. to research a single module it take 800K research.. you would spend a lot of time just to get there.
