Hub brakes are more than plenty, the difference is that you can't go from 15-0mph in a very very short distance like rims/disc brakes, it's pretty hard to lock the rear wheel with that brakes alone (apart from coaster brakes).
With both brakes applied, it's more than enough to slow you down, and being internal, it won't need constant adjustment to keep it predictable, one less thing to worry about, my brake on my bike is already pretty worn by 2 months and end up needing to adjust it (and clean the rims).
On the old dutch bike that weight as much as a Nissan SUV, coaster brake and front drum brakes were enough to stop, even with the missus on the rear rack.
Having says that, it's not worth using on a bicycle for racing, that's where it won't work well.
