That’s a good point, and I agree with you. If you create enough laws, you can pick and choose who and when to enforce them against. This is also a road to tyranny, and it exists today at the Federal level, because the Federal government was not held to the supreme law — the Constitution. The Federal government was never supposed to have police powers at all. That was the job of the states, while the Federal government was to be constrained to enforcing regulation on the state governments themselves.
Nevertheless, clear, objective, and uniformly enforced law is the foundation of justice. Justice, remember, is blind.
