You are only focusing on the portion of the Path card that grants you the Destiny. You are completely ignoring the condition (the one that I keep emphasizing) that states that you have that Destiny " FOR AS LONG AS YOU ARE ON THE PATH ." That's as good as saying, "You cannot lose the Destiny." Why? Because you have the Destiny " FOR AS LONG AS YOU ARE ON THE PATH ."What you failing to understand is that if the Path did not say "treat as having the destiny" the destiny would just sit there on the Path and it would do nothing until you complete the Path. But because you do treat it as if you have it then it can be targetted by effects that effect your destinies.
The only way past this is if the Path had a forbidding effect like "you cannot lose the destiny while your on this path" it does not say any forbidding effect take this as a example.
Show me the conditions where you can be on this Path without having the Destiny. These conditions must satisfy the condition of the Path where you have the Destiny " FOR AS LONG AS YOU ARE ON THE PATH ."
In other words, how can you simultaneously be on the Path and have the Destiny that is guaranteed to you " FOR AS LONG AS YOU ARE ON THE PATH " and be on the Path and NOT have the Destiny that is guaranteed to you " FOR AS LONG AS YOU ARE ON THE PATH "?
You can't have it both ways. Either the card is true at all times or it isn't. There are no conditions listed on the card that state that you can be on the Path and not have the Destiny. The Path and the Destiny are one. The only way to lose the Destiny is to lose the Path.
Thats right there is no condtions listed on the card that forbids the loss of the destiny, the path does not say "the only way to lose the destiny is to lose the path" it says "you count as having the destiny so long as you are on the path" its as plain as day there is no guarantee because there is no forbidding effect that stops the discard.
But again Like i said looks like we have to agree to disagree ive explained it as best as anyone can.
Answer this question (which I have previously asked twice now, and which you have previously not answered twice now):
The Path guarantees that you have the Destiny " FOR AS LONG AS YOU ARE ON THE PATH ." What game condition(s) exist(s) where you can be on the Path but not have the Destiny that is yours " FOR AS LONG AS YOU ARE ON THE PATH "? Answer that question. Please. Show me how you can not have the Destiny that is guaranteed to you " FOR AS LONG AS YOU ARE ON THE PATH ." How does losing the Destiny fulfill and satisfy the condition of the Path where you have the Destiny " FOR AS LONG AS YOU ARE ON THE PATH "?
