Should they? There's lots of things that are currently crimes that I don't believe should be crimes, so I have no reason to support policing in at least those cases.
The problem with rats' nests of infrastructure is that it is effectively impossible to determine what wires are structurally load-bearing in unexpected ways, and there's literally nobody in a position of authority that would be even remotely trusted by a super-majority to construct a suitable replacement system from whole cloth.
