and what's being said is just as simple. I can wield a sword, it doesn't make me a swordsman though :/
i can be a chosen hero who uses a sword in the future, doesn't make me a swordsman right off the bat.
Thats a nice analogy but.......
Q5: Why was Riku chosen as the original wielder of the keyblade?
A: Because he was chosen by Terra to inherit.
To use a keyblade you must have been chosen to inherit as well as been chosen by the keyblade itself. In BbS you could see that Terra performed the ceremony with Riku, and that is why Riku was able to take the keyblade that Sora used.

Terra looks at Riku as he performs the inheritance ceremony.
[picture: Little Riku looks at a door with a keyhole.]
Because he has been chosen to inherit, Riku can see the keyholes of the world.
BOO YAA!!!!!!
