I doubt this was your intent, but my reading of your words kind of leaves me thinking that someone with no background knowledge would leave thinking there is(!) great known danger with at home LSD use, and also that achieving results reasonably equivalent to some of the outcomes described in clinical studies requires(!) the counselling that accompanied it.

As for now, the only evidence that can answer such questions is anecdotal user stories, of which we have lots, and from my reading in that realm, while there is undoubtedly very real risk involved the vast majority of feedback is positive.

If someone who could benefit from these substances is in a position where they are unable to obtain professional services (most people I'd think at this stage), it would be unfortunate if they didn't bother looking into it because of reading overly protective risk assessments.
