The unfortunate and sad reality is that constitutionally limited government is an abysmal failure.
When the government being limited by constitutional law is also the entity that determines the meaning of the limits and how the limits are enforced then the government will actively erode the original intentions in favor of itself.
Even the founders were aware of the risk of erosion and expected the peace to be much shorter lived than it has.
