No, that is exactly what we don't need. When law becomes out of step with modern sensibilities, the law needs to be changed. Precisely the problem we currently have is that we have become too accustomed to dealing with a sort of "shadow law" system where the way things actually work is not the way they're supposed to work according to the law. That is a recipe for confusion, bias, favoritism, and inequity. What we need is a system of laws that actually lets the people fix things when they are broken instead of patching around them. (This is, in my view, a byproduct of other aspects of our legal system, in particular the grossly over-restrictive process for amending the constitution.)
