Does psychology overstate early childhood experiences as the primary cause of mental illness because psychological intervention can change maladaptive behaviour but not biology?

Just to clarify, I’m not asking a broad ‘nature vs nurture’ question. I’m wondering if in your view psychologists and therapeutic modalities as a whole have a tendency to overstate early childhood experience because behaviourism is efficacious and biology is complex and difficult to treat.

Changing maladaptive behavior is changing biology. The mind and body are one thing. Changes to how you think are reflected in neuroplastic changes. 

Experiences matter and earlier experiences matter more because the brain is more easily influenced earlier in life. It used to be thought that childhood was the only time your brain was plastic at all. 

A person never exists independently of their experiences. Epigenetics is the science of how experiences impact genetic expression. 

Psychological modalities are about treating problems that are best treated through subjectivity. It is work on the part of the patient to treat something like a personality disorder or trauma, a patient has to participate in their own healing. In many cases, due to the materialistic worldview that is currently fashionable patients resign themselves to something like biological determinism.
