My first thought was, "No, that's not how point expenditures are balanced." Character points are fungible, so any points the character can't spend on one thing can be spent on something else of roughly equal utility. If we're talking about a VPP (under 6e), the character buys the Control Cost up to their limit and receives no compensation for not being able to buy it higher.
My second thought was, "Well, what about Adjustment Powers?" In theory, a character could be operating with a reduced EGO and not have access to their full powers. How often is this going to happen? If that character frequently has their EGO Drained or Suppressed, "Limited to EGOx3 Active Points" might be worth -1/4. Otherwise, it's -0 (but an opportunity for great role-playing when it happens).
