The main point of fairings is looks. They also provide some aero advantages, but you wont be able to tell untill you break 100mph.
As for falling, the saying goes "its not if, its when." Personally I think its more like "its not when, its how many times over". Sure you might be the one guy in a thouthand who doesnt fall, but you are better off preparing for falling and being pleasantly suprised than riding around with no gear and no frame sliders and later messing up yourself and your bike.
I consider myself to be a pretty good rider, yet I've dropper and crashed every bike I've owned. Not only that, but I will likely crash many, many more bikes before I'm done with this sport. It just comes with the territory. Bikes fall. They make crunchy sounds.
But in case you think I'm just some young punk, check out a post by Dad. He had something like 130k miles on his bike, either half a million, or a million in his riding career, been riding longer than I've been alive, and recently messed up a corner.
Its a full contact sport.
