Because cars are designed with a proper center of gravity in mind. This negates many factors of handling and can cause unexpected behavior of a vehicle if it is driven while raised like that. It also affects the camber, not allowing all of the tire to be in contact with the road on the front end. This affects braking and steering and makes the car more likely to hydroplane. Also if an air bag failed while lifted and driving (which has happened), it could result in an accident that could have been simply avoided.
There are other reasons as well but these are they main focus of my statement.
You don't get out much do you?
Been around for years: Lifted trucks, huge tires, hydrolics, air bags, lowering springs/control (camber)arms, big wheels, big brakes, c-notches.......There's nothing illegal about any of those if done properly. As for a bag blowing, it's not as bad as you think. A friend had one blow, and it wasn't anything to freak out about. He just had to fix it on location because he was dragging a corner of his bumper. Hell, you could have a spring break, too. Ever seen a leaf spring break? Not cool, lots of damage. There's not a material in the world you could use there that would be 100% guaranteed not to malfunction.
*there are also tires designed specifically for cars of +/- camber also
