It just needs to be lowered. Right now the station uses 1 robotic component every ten seconds, and wastes 40.000 worth of repair power on 360 worth of damage. Or even worse, with both robotic components and hull panels it's 80.000 worth of repair power on the same amount of damage. The station should take damage less often, in larger increments. Right now you need 8.500 robotic components every 24 hours to maintain your base - provided it doesn't get attacked, because if it does, those robots won't save you.
Besides, bases are very common in the world of Freelancer. I mean, dozens of them get blown up every day in missions. Why can't players grow their own the same way?
Also, it's much cheaper to maintain a small base by doing the following (again, taking attacks into account is pointless, so don't):
-heal it up to 8.000.000 hitpoints.
-remove all hull panels and robotic components from its cargo bay
-wait like two days, your station will survive that
-heal it back up with like 200 robotic components
-repeat
So, instead of using 9000 robotic components a day, knowing it's gonna blow up ANYHOW if someone wants that, the same amount can be used to last you three months, provided you log-in every two days. The numbers are rough, but you get the picture.
