You have no evidence for that. Yes and no. Someone (e.g. Hashirama and Naruto) can train till they are able to absorb natural energy effortlessly, just like Juugo. But also, they still absorb it of their own volition, unlike Juugo. But tell me, which other kekkei genkai can be replicated by simply applying some ointment? No kind of ointment can make a normal eyes become a Byakugan or Sharingan, whereas we have one that can replicate Juugo's so-called kekkei genkai. Sorry, but your hypothesis is too shaky.

There is nothing left to discuss on this issue, and you have the right to hold onto your hypothesis, but save yourself the effort of trying to argue that it is tight in canon, because it is absolutely full of holes as I've thoroughly pointed out above. I still respect your opinion/theory, as it is a competent one.
