The main reason for running those rub rails from MC is partly the same as what you're asking and that is a little standoff to keep things off your body. I might be wrong here but that's how I see it.
The difference between Metalcloak flares and a functional rub rail has everything to do with leverage and profile. Flares are not rub rails, nor should they be treated as rub rails.
The reasoning behind this is very similar to why some chop the tube steps off of the Genright mini boatsides.
