Not my point. You said basics of haki were obtained through either training with a teacher or by going through something emotionally tough (anger/pushed to the limit), yet Usopp debunks that claim. My point is that you're pretty much making up your own rules about how haki works, be it for basics of hak or "haki flowing". It'd be ok if you only presented this as your personal theory, but you're trying to establish rules that were never established in the verse.
