Questions regarding the locked room

1. Is it entirely a symbolic thing? I've noticed JKR tends to be 
mechanistic even when working with metaphors.

2. (assuming it is more than a metaphor) if the room is always 
locked, then what is the point having it at all?

3. What would have happened had Harry succeeded opening the door?

4. Since Harry has in abundance the force that is in the room 
(whatever it is) could he (unlike others) open the door without any 
damage done?

5. What would have happened to LV if someone would have kicked him 
inside and lock the door on him?

Just wondering aloud.
