Could be? Yes. But I don't know if it's super clear that any existing technology would solve the problem without also introducing new process changes. For example, I can imagine a world where the laws are just a bunch of text files and instead of using git to make changes, we just add a new text file and there's a preamble that says that the law is superseded by any future laws. Laws also aren't as clear cut as code. We have tons of contradictory laws on the books today.

What I'm getting at is that, if we need to make process changes anyway in order to actually make the technology work for us, then the real solution is in the process and not in the technology.
