Not unsolveable? The Constitution was written to restrain government, but government has given itself exceptions to every restraint. We have no power to reimpose those restraints.

We have the highest incarceration rate in the world, global military conflicts without any declaration of war, confiscatory taxation, micromanagement regulation, licenses and permits mandated for everything that isn't outright illegal, and a byzantine legal code that makes anyone a "felon" if anyone cares to investigate enough. That is a failed system.

Even with a written Constitution and an explicit bill of rights that reinforces the idea of limited government to explicitly-granted authority in the 9th and 10th amendments, the leviathan state grew like a cancer.

That is failure.

As Lysander Spooner said 150 years ago, "But whether the Constitution really be one thing, or another, this much is certain - that it has either authorized such a government as we have had, or has been powerless to prevent it. In either case it is unfit to exist." No one has demonstrated practically that he was in error sincce then.
