Your point cannot be overstated, I find scrum great for new product work, but pointless for maintenance that comes in ticket by ticket. HOWEVER; The counterpoint would be if you are doing new product work and your priorities are changing faster than a week or two you have either an exceptional situation or this should be a canary that you have something really wrong with your priority directions. In the latter case scrum is being a useful tool in bringing this to your attention.
