Why do some doors open inward, and others outward?

Is this a design choice, or is there some reasoning behind it?

Residential doors are attached using hinges held together with pins. To remove one of these doors, all you need is a hammer and a flathead screwdriver to push the pins out of the hinge.

This is great if you need to remove a door, but if these hinges were placed outside of the room, anyone could pull the pins out and gain entrance. By having the pins inside the room, the door must open inward. Closets have doors that open outward to conserve space.

Commercial buildings need doors that open outward to make it easy for people to leave the building if there's a fire. When people panic, they rush to the exits. If the doors swing inward there may be so much crowding that the door can't be opened. These doors are made secure by using pocketed hinges that fit into the door frame. This is more expensive than a residential hinge, and the door becomes much harder to remove.
