I believe that you are saying to start from the top and go down rather than start at the bottom and go up.
Perhaps just as effective, in terms of psychologically crippling a civilian leadership intent on imposing a tyranny, would be a credible threat to eliminate their families. Such a credible threat could paralyze the would-be tyrants even before they took any irreversible steps toward tyranny.
It is all an economic equation - raise the cost of anything too much, and no one is interested in buying. This is, in my view, the specific reason for the existence of the Second Amendment - to let future would-be tyrants know that the liberty-loving populace would be armed.
Besides, if they threaten the families of those who would resist the impostion of a tyranny (which they clearly do), well, there's always "collateral damage" on both sides in a war.
Molon Labe! Sic Semper Tyrannis!
