I completely agree that the profound experiences you can have during psychedelic trips can be life-altering. I don't know whether it's the experience that leads to the other benefits, and if it doesn't, I see no reason why one would have to get them bundled.

The OP's comment reminded me of a some people I've come across that were into meditation and were anti-psychedelics, and to me it seemed like their main issue was that you could get these very deep experiences like ego-death but you didn't earn it, you didn't sit and quiet yourself for months and years, you just popped something into your mouth, experienced a bit of nausea and were teleported into a different dimension. It always seemed to me that they felt cheated because they took the hard road and felt that it's unfair that others took a short cut. Needless to say that it was even weirder given that they also tend to talk about compassion and inner peace a lot.

I totally understand if you believe that you simply cannot separate the psychedelic from other parts because it is what gives the benefits. I did get the feeling that that's not quite it though, that there's a lot of "and you shouldn't try to", and that feels like "you shouldn't get the benefits without embracing the experience, potentially encountering your demons etc", or a religious practice surrounding it.
