That's not true. There is one trait that's absolutely mandatory before you can work rituals: Thaumatology. Without having at least 1 point in that skill, you explicitly cannot cast spells, period.

With no underlying mandatory trait, there's nothing you can apply Limitations to, nor is there anything you can "sell off" during character creation if you wish to create a character who absolutely cannot use magic, in exchange for a modest bribe in CP.

That'd be Incompetence (Thaumatology) [-1]. In a campaign where RPM is the magic system, the ability to understand and cast spells is skill-based, so whether you can cast spells is a question resolved on the same level as whether you can swim, cook well, or drive.
