Regarding too many restrictions: I know a case where a gal just tried to interact with a guy coming from a place where restrictions are too severe and later look what happened: When she met that guy in the lift then he was giving the room number and saying what not.
Too many restrictions may slow down the intellectual and physical evolution. On the other hand. too much openness is like greedy algorithm (being tired I need to check later if freedom is really analogous to greedy algorithm or not) which may fail to provide optimal solution and may lead to instability.
I will extend the points more later
