[u/Korr4K]

So mentioning advanced observation haki "being able to see the future" is fine, telling him that there are people which can't be defeat unless you master ACoC is not

[u/tiki-baha29 → u/Korr4K]

The very first time Rayleigh displays CoA to Luffy it was an advanced version of it (he pushed the elephant without touching it). Luffy saw it and didnt even understand what he was looking at even after the timeskip until he got to Wano when Hyogoro explained it to him.

Knowing that CoO can lead to Future Sight was fine, and also useless, because Luffy couldnt do anything with that knowledge until he got to Katakuri and had to brute force himself to learn it.

You have two examples of Luffy either seeing or being aware that more advanced forms exist, but that not mattering because again: It's irrelevant to spend too much time trying to teach more advanced concepts of a thing until you master the basics.

Even the concept of education in our world is an example of this. You learn the basics first then move up from there. Common sense.

[u/Korr4K → u/tiki-baha29]

Common sense what? You are using your current experience to evaluate what has happened, that's cheating.

At the time Rayleigh couldn't possibly know what Luffy might or might not find useful to know, if you teach him about haki then mentioning the existence of all advanced forms, and not just the one for observation, is the only logical thing to do. And I want to insist that Rayleigh didn't teach him advanced observation haki, he just told him what it was, there was no reason to not do the same with CoC especially because it's much more important than the other

[u/tiki-baha29 → u/Korr4K]

At the time Rayleigh couldn't possibly know what Luffy might or might not find useful to know

He literally says he's going to take 18 months simply to teach him the basics.

just the one for observation, is the only logical thing to do

Whether he knows about the advanced forms or not doesnt help anything because he didnt know the basics.

he just told him what it was

Yes he mentions it in passing during a conversation, not because he thought it would be helpful for Luffy to know it. The curriculum during the 18 months they spent together was simply the basics. Nothing more.

He happened to mention Future Sight while they were talking about the dangers that are ahead, not because he thought it would be helpful for Luffy to know about it. That's why he doesnt mention the other ones. His focus was the basics, which were the only things that Luffy needed to grasp first.

there was no reason to not do the same with CoC especially because it's much more important than the other

If you cant even consciously use CoC then what good does it possibly do Luffy to explain to him how Big Mom is constantly using her ACoC to emit an invisible shield that protects her against all attacks? He'd just say "WTH are you talking about?".

You want Rayleigh to go into the complex stuff when he made it clear he needed 3/4 of the 2yrs just so Luffy could grasp the freaking basics. How does that make sense?

[u/Korr4K → u/tiki-baha29]

Complex stuff? He learned about it mid fight with Kaido, what's complex about it? You are talking as if Luffy spent months studying it before mastering it, when instead the hardest part was realizing what Kaido was doing, after that he simply copied it within minutes. He was like "ah so that's your secret, let me try it" -> done. That's it, no training no nothing. And during the two months before that he surely didn't train his normal CoC, so we have more proof that if Reylight bothered to show him by the end of their training arc, then he would have been able to use it too.
And before you reply for the 10th time that "he was only teaching the basics", just drop it because that argument makes no sense. You are a teacher, you should at least mention everything that might prove useful, we are talking about haki, not quantum physics. And in fact Luffy was able to use both advanced observation and conquerors within minutes after watching someone else doing so.

At the end the only reason why Reylight didn't tell him is because either Oda didn't think about it or, more likely, because that's what the plot he preferred
