A robust internal frame stops parts moving relative to one another. Without it internal component can flex and bend a great deal more. A rigid frame also creates a solid feel to a body which is very good for handling.

The use of Magnesium is an engineering choice for combined low mass and high strength properties. The ideal material would be Titanium, but it's rather more expensive ( about 200x the price of Magnesium ). If you know of something cheaper that has similar properties to Titanium then for goodness sake tell people because there's a huge queue waiting to form at your door, cheque books at the ready.

It seems better to add a thicker rubber coating to the camera to provide more protection than a stronger frame.

This would absorb a negligible about of shock and either add a great deal to the size of the body or force a more constricted internal design. It would not provide any rigidity at all.
