If a nation were to maintain rigid procrustean laws throughout history, without any amendments, we would have a very stiff system that would not allow for new ideas and new opportunities. With new times come a new set of constraints which must be imposed. Some laws are added, some taken away, because societies are always changing. Simply because a legal system may be slightly flawed or liquid does not mean it should be ignored. The costs of such a measure are far beyond the benefits of civil obedience.
