Sure, but the US constitution also prevents "taking" without compensation. That "taking" can also include you keeping the property but the government imposing new rules that lower it's value.
Do you have an example? I'm not aware of any instance of a general change that lowers property values causing the gov't to have to compensate landowners. The "taking" of which I'm aware is use of eminent domain to expropriate land, which requires fair compensation to the owner.
