I assume at the time of the Whiskey Rebellion, we didn’t have a president who disregarded election outcomes (including the outcomes of congressional elections) and did whatever he wanted, stayed in office as long as he wanted, tried to rule by decree, etc. Once you do that, there’s not even the veneer of legality to any of it. You are just declaring yourself president-for-life and trying to get the military to back your naked power grab.
