Plus the fact that King Frederick Wilhelm IV of Prussia was held hostage in his palace by Revolutionaries until he signed a Constitution alarmed King Louis. I'm sure it must have brought back bad memories when he and his family were forcefully kept prisoner by a mob at the Tuileries Palace.It was a sane measure that would be followed by almost all monarchs in the world. Opening their own palace meant that they are vulnerable to assassination/attacks, Louis XVII closing the Palace to most people is understandably unpopular, but as the Republican Assassination of Queen Victoria of Britain has shown everyone, that some sane security measures are indeed required.
The assassination of Queen Victoria was a huge event that set off shockwaves in Europe. It paralyzed the British government and created chaos in British politics. Louis XVII ever the opportunist used the opportunity to strengthen his own expansionist ambitions in the wake of his adversaries misfortune.
OOC: Good point actually. I feel like a delayed regency might happen due to the fragile state of Louis' constitution and mental health.OOC: there might be more struggle of power behind the scene, considering he's THE frickin Napoleon. At least this time he knew when to call it quits with grace, of all things
