Assuming D&D lore, polymorph fixes that problem pretty easily. A polymorphed dragon could blend into society pretty well, and if you want, you could still get a ride into international waters (to avoid setting off national airspace warnings), fly down to some random jungle tribe, and be worshipped as a god. Plus nigh immortality (assuming aging only affects your polymorphed form and you continue to age at the rate of your dragon-self).
