With our right to roam, who needs paths anyway. One of the best ways to climb the hills is to go 'off piste', cross country.' Every man, his own path maker', so it goes, then there wouldn't be any problem as a route used by someone XC would be different from someone elses, so there wouldn't be any erosion, as grass and heather would not become so damaged and quickly regenerate.
Just a dream I know, but I often prefer to get away from established routes and find my own.
