Is it really that challenging or just not a place to face plant? Much of it looks like an easy ride with the grade going sideways. Unless there is poor traction, risk of a fall is low. So then it is only about keeping focus away from the fact that a fall = certain death ...

I would not do it of course. I like mt-biking but have just as much fun with a technical single track that doesn't guarantee my demise when I fall.
