The problem of RSI isn't QWERTY, the problem is putting all your fingers on the home row.
Type with your hands at an angle, and your wrists inline with your arms and palms. Problem solved.

Stretching the fingers for reaching a given key is bad, Dvorak masks this by minimizing travel, which is simply a workaround / optimization for the wrong thing that long-term will result in the same problems (simply delayed a few years).
I could use an intentionally bad keyboard layout and it wouldn't matter. Arms are designed to be moved.
Not at all! RSI is complex because it can involve a hundred muscles and tendons. People can have inflammation and pain even in wrists, shoulders and elbows due to keyboard use.
Reducing finger travel by using Dvorak can be very beneficial. Obviously it will do little for things like ulnar pronation.
