The point isn't to reduce prices, the point is to make sure that prices accurately reflect costs. In this case, prices do not reflect the cost of parking, which lets some people get away with not paying for land in the city, even though they use land in the city. If this increases prices, that's good, because it lets people more accurately understand the cost of their habitation and transportation. Alternately, if that's bad, I think the burden of proof is on you to show why inaccurate pricing results in more wealth overall.
