Dude, high wing is more stable - it's called the pendulum effect.
Imagine your a/c is disturbed in roll (gust of wind under the wing for example). The resulting sideslip causes some air to bunch up under the fuselage-wing joint (in it's armpit) on the downhill side. This gives the lower wing a bigger pressure difference betweeen bottom (now higher) and top (same as before). This moves the centre of lift from the centre of the wing span to some position slightly downhill from the centre, thereby tending to rotate the a/c around it's longitudinal axis i.e. roll back towards whence it came i.e. it is stable.
You can't make this scenario work with low wing. Therefore high wing aircraft are inherently stable just because their arms come out their shoulders not their hips.
As for scraping wings - what the hell are you doing with the wings that far over? I've never (in only seven years flying mind you) heard of an aeroplane that has enough rudder control to beat the ailerons in a classic XW technique at landing speed. I've only ever run out of rudder, not aileron. IMHO the wings would never get close on any (light) type because you'd run out of rudder first in the classic crosswind technique. Except in a Moth, and then you're just out of options! (Good thing they raised that bottom wing).
And DT - high wing is better for scenics, but low wing is better for travelling pax because it gives them the feeling they're sitting on something rather than hanging from something.
Most passenger planes have the engines underneath the wings in order to keep the air smooth over the top, but in a high wing that puts them in the way of the view for the pax! All they can see is down down down.
Last one I can think of - if you build a wing section and plonk an aircraft on top it will sit there coz the wings push up and gravity pulls the fuselage down, but if you hang the fuselage underneath it still wants to go down but the wings are still trying to go up.
It may sound like I'm all in favour of low wing, but they don't keep you dry if it rains when you're getting out, and I'd still rather have the back seat of a Tiger Moth anyway.
