I suppose that may be true, but for the cost of a capacitor you could nearly be get a power cell that even further reduces the draw on other components due to its storage of electrical energy as well as its ability to quickly supply it when needed.

The main issue that i have seen, especially at a couple of the car audio shops in my town is that they pretty much recommend a capacitor to anyone having charging system issues... so people are spending hundreds of dollars on a capacitor plus the installation that doesn't really do much when thy could be spending that same amount of money on components that will actually remedy their issues (alternator, batteries and wiring).
