Any system has to take into account "bad actors defying the way it originally worked"
No system can survive the top authorities
refusing to enforce the system. There is no way for a singular establishment to provide checks against
the checks themselves being taken over by bad actors. The
attempted check against this was separating the authorities of governance so that the interpretation of law, passage of it, and enforcement of it were not under a single body.
Which worked through at least one full turnover of individuals in power, mind you. Multiple generations, every last person involved in setting it up was
dead, as far as man-made systems are concerned that is a
fucking amazing performance, and it continued to improve the lot in life of the general public for nearly a
hundred and fifty years.
The fundamental problem with your comprehension of the matter is that you
wrongly see social pressures and tradition as far more resilient than
actual laws, because you perceive formal rules as more fundamentally arbitrary than peer pressure. People can look back, read the Founding Father's writings, and
know that the 2nd
originally meant privately-owned warships.
Meanwhile, you have to make enormous backflips and extrapolations to have the remotest grounding in actual history for your position because the day-to-day operations of Monarchies you adore
weren't written down. Your goals cannot be achieved, because you do not actually know what you want to go back to, because
it was not written down.
You have to make enormous guesswork and engage in very complex and
risky reconstruction efforts to recreate the "old ways" damned near from scratch, whereas US revivalists can crack open volumes of the Federalist Papers, comb over records of the debates, and read the Constitution to get an
extremely detailed and accurate view of what the Founding Fathers intended.
This is the fundamental issue with relying on "tradition" or "social convention" or "Christian morality". Any change that occurs is obscenely difficult to reverse, because the previous state quickly becomes unknown. Meanwhile, the US almost
routinely brings back fights older than the people doing it because
we wrote the system down.
