Yeah the Conjury storyline points out an outlier of a person, someone rare, someone able to draw from their own lifeforce to do anything - that doesn't happen naturally. There's just no support for that in lore. Yeah you can learn Conjury wrong, but it would most likely mean you accidently use wind instead of cure or your Cure's are worse than other peoples (But you give no care's because you're still helping people) using the same Aether as you. That stuff is actually kind of an interesting character development, since there isn't anything "tragic" in it - as people like to do so often.
The cannibalizing of your own aether isn't natural - while learning you just aren't going to do it accidently. It's implied that that is effing dangerous and weird, so I'm assuming they wouldn't just teach anyone as openly as they do if it was just a thing that happens in your first lesson (The THM storyline supports this, as they will turn people away without the proper Aether reserves). Is it impossible? Of course not, some students are going to do it naturally. SOME like 2%.If you play that 2% that's up to you, but don't try to defend it as not somewhat special snowflake-y.
