Note that you can combine two such traits, and their effects will add together. You coul make them both -500 and 20% penalty (example values of course, not saying these are absolutely balanced values). Take both, gives 1000 points and provides a 40% space penalty.

If you have trait A with -20% and gives 500, and trait B with -40% and gives 1000, you can take both to get 1500 points and have a -60% penalty.
