Changing gears using a front derailleur is a pain in the ass, but cleaning and lubricating the chain (+casette +chain rings) after every ride in the rain, is not?! When it's not raining, there's also the issue of dust. You don't need super duper brakes for casual riding, hydraulic disk brakes are good enough without much maintenance, maybe just once per year. Unless the tires are skinny, they shouldn't puncture very often and replacing them isn't that hard or expensive. You won't break any speed records with a belt and an internal gearhub, but they aren't that inefficient especially when you don't waste time or money cleaning the traditional drivetrain.
