[Star Trek] Living in a holodeck full time?

Would you be allowed to live out an alternate life in a holodeck if you were a citizen of the federation?   
  
If I wanted to live a life in the past or be the ruler of a plant, could I do that in a holodeck?   

What taboos would not be allowed in the holodeck? Could I reenact D-Day on the holodeck or or explore darker sides of humanity? 
   
The alternative would be to actually go back in time and last time I did that the future starfleet didn't like that I took over the Moon and made an advanced race of moon people.

Re-enactments of battles are fine, in DS9 Miles O'Brian and Julian Bashir re enact the Alamo and WWII battles all the time and it's all seen as good fun. Wanting to live in one full time though, that's going to get you some looks. Sure you technically could, it's not illegal or anything, but your friends and family are going to become concerned that your life is ruled by fiction. They may even call in a counselor to diagnose you with holo addiction if they feel it is appropriate, same goes for exploring "darker" fantasies. The people of the Federation may be extremely tolerant, but if they feel that you are a danger to yourself or others due to your actions (maybe those dark fantasies won't be enough and you'll start craving the real thing) they are not above sentencing someone to a rehabilitation center for their own good.
