You're not entirely wrong, but you may also have a similarly limited understanding, having never been completely in thrall to an addiction. I know many recovering addicts who have white-knuckled through recovery-from-surgery (including blunt trauma from a propeller, partial hip replacement, and major oral surgery) in order to preserve their freedom from (what they described as) the intense suffering that failing to continue their recovery-from-addiction would entail.

We are all allowed to have different subjective experiences. Nobody is "wrong" here.
