"Literally everyone involved in the treatment and support of substance abuse" is a small percentage of the population as a whole, and a very, very small percentage of the people who make policy and resourcing decisions related to how substance abuse is handled.

You may be in a particular microcosm that handles this well, but that is definitely not the universal experience (not by a long shot). I'd also dispute the "literally everyone" part of your comment, as I can think of countless examples of attempts at substance abuse treatment and support being actively harmful to the person struggling with addiction.
