Horses did work, and would still work if we still used them.
But for an official service to necessitate a physical form lettered to them, that is simply unnecessary overhead for the individual, for society, and for the environment.
I'd rather have to rely on physical mail than have to rely on a smartphone or other digital device for dealing with my government to be honest. Better to have the choice of course but if it would be only one then the former might be an inconvenience but the latter can turn into a real nightmare.
