I strongly disagree. Your circles might be different, but in my experience, wanting to do your homework makes it less accessible, because it tends to put you at odds with the people who are otherwise eager to grant you access. They want people with a certain mindset and an up-front faith in the process. They want people who aren't careful about ingesting psychoactive substances, are eager to put their mental health in the hands of some guy they barely know, and are going to blame their own baggage or spiritual shortcomings if it doesn't go well.
These drugs, and many others, are already pretty accessible if you are willing to take that heedless approach.
In contrast, the approach described in the article is expressly tailored for people who want to be careful and do their homework. It's for people who have access to the drug and implicitly already have access to cruder ways of using it, but who want to put in extra effort for a more controlled experience.
