The simples hurdle just being knowledge.
The existence of NAS is probably an unknown unkown to a large part of the population.
Compare that to "there's an app for that" & plug USB.
Drastically simpler.
No skin in the game either way, but I can very much understand OPs reasoning and would reach the same conclusion.
