You seem to be mistaken about how their policy operates.
You're also working from a different premise than me: I believe people fundamentally have agency, and so they're influenced by their circumstances, but their problems are not causal from them -- they made a choice to adopt that habit as a coping strategy.
And frankly, I disagree with you about how to confront that: I think we should be accepting of how they got there, but I absolutely disagree with things like HAES which suggest that their choice isn't a problematic one.
To borrow a phrase from a friend, and use it somewhat out of context: I can love a sinner without enabling or accepting the sin.
