This view ignores the major application of these substances. Ketamine-induced self-therapy is accessible instantly and acts as a major reset. When you are experiencing long-term depression and/or anxiety, the advice to "just meditate" or do deep introspection is wildly counter-productive. Depressive state is very frequently accompanied by an unhealthy focus on the internal voice and on over-analyzing own life/motivations/purpose/etc. Having an "introspection session" in this state is a borderline dangerous advice.
There are corresponding risks to this, of course, but that's the flip side of their utility as a (sharp) tool.
