And having the same properties does NOT answer the question. How is Senjutsu having the same properties as Nature Chakra a counter? After all, casting a Katon against another Katon doesn't automatically translate to a victory as it does in this case. So, I ask again, why does Senjutsu counter Natura Chakra? Neither you or KYF have answered this question properly.
I just want to point out Num, that your statement concerning diamonds could also be applied to this situation. Senjutsu is after all the combining of Nature chakra with the other 2 chakra types (mental and physical energy) people naturally have, to create a far more powerful chakra, that could be considered superior to "raw" nature chakra.
It could also be comparable to the nature of Haki and Logia users from One Piece. Normally logia users are completely intangible, but if their adversaries are capable of infusing their attacks with Haki they become tangible again, allowing the attacks to hit them normally.
