I'll agree with your first point, but not with the second. A messenger bag carries the weight lower and if you are wearing it properly, better balanced than a backpack. A bag with a stabilizer strap, a good fit, proper packing and setting it up properly are necessary, but I much prefer a messenger bag for comfort and stability.
