I am fully aware Destiny is an always-online game. All the same, there simply needs to be some pause option in Destiny. Provide players the option to pause themselves, rather than pausing the game. If you're playing solo, maybe the game just puts your character in an impervious stasis. If you're playing in a group, provide the group the option "vote to pause" and something similar happens where the group is in an impervious stasis. You never no if something might come up and interrupt your game. It could be an emergency like the pizza delivery person knocking on your door haha.
