Nope. If it's your reality, then you can do absolutely anything you want. Other people will have to play by your rules (if they want to be in your reality).
This is the same as if you created your own private video game.
If you actually want to interact with other people in a 'shared' reality, then of course you would have to follow rules set by whoever created that reality.
My point was you'd be free to create your own reality, limited only by your imagination.
