If words can be interpreted to mean anything to anybody, then communication breaks down and culture moves toward anarchy. Once words no longer have an absolute meaning, the purpose of documents becomes irrelevant and courts are free to make decisions based on whatever criteria they desire.
Law becomes arbitrary based on opinions and social norms.
In some societies cannibalism is considered normal. In many ancient societies slave prostitution and human sacrifice were normal. The evidence for increasing anarchy in any culture is increasing violence and crime. Since people cannot live with anarchy, they will sacrifice personal freedoms in order to allow the state to re-establish order. However, in doing so, the major checks on the absolute power of the state, such as the amendments to our Constitution, are sacrificed and ignored.
