It just doesn't seem like much of an issue. The point of the ability is that it penetrates the defenses of whatever it hits, be that a shield or flesh or a wall, there is no means of blocking or defending against it, so the first explanation would be a falsehood and would give people the idea that with sufficient power or defenses they could get away with blocking it which goes against the point of the ability.

Jiukundao work as an interpretation of the event that killed the wielder (Or will kill them as we discussed for the Souzoushin as they never technically died). Tai Sin was torn apart atomically as a Human when he was lured into Hueco Mundo by a Hollow playing cat & mouse with him. Essentially he was smothered until he became nothing, his Jiukundao interprets this as "nothing being in the way" when it makes an attack. As for what powers it, there's clearly some spiritual power necessary for it, they're spirits after all, but I take it to work on the same basis as Orihime's, that his resolve to keep going in search of strength allows it to work.

Aside from being unlucky when he attacks someone one, and they reciprocate, he could just keel over (Given his current form) if his believes are shaken.

On the other hand... I kinda wanna make The Ostentatious now.
