Either that, or change the law so that it becomes enforceable, or spend more resources on enforcement. If the law is enforced in, say, 1% cases, why is it even there? Most people who break it face no consequences, and it has a potential to be a tool to unfairly target people ("we want to destroy you so we will find a law that you're breaking that is normally not enforced and lock you away for that").

As for the specific example, yes, I think felons that served their sentence should have their full rights restored.
