Should I continue Taekwondo after transferring from ITF to WTF?

[Acronym]

So if you don't go in to a traditional stance, what is the problem with Kukkiwon Taekwondo's short stance? It's a training aid the same as the other stances, and it's a natural stance (the one used in walking).

Who cares about walking? It's not a natural stance for striking. You ideally have a certain bend in your legs.
