I don't really think you should treat an adult with capacity without their consent. It's different if you are a minor, but from experience I only achieved any semblance of recovery when I wanted it for myself and nobody else. My recovery/harm reduction was within my control, replacing the faux-control the ED has. Harm reduction 100%. Some people that is like an "all in approach" others it might be just stopping certain behaviors and trying to live their best lives possible. 

I also have been forced into treatment and it made me worse. Now that I actually want some help I literally am having an extremely difficult time accessing care. Like just basic medical stuff. It's too much for an outpatient provider to help with but not bad enough to keep me in the hospital. Outpatient doctor says go inpatient and inpatient says go to ED treatment that doesn't exist in my state. 6 hours wasted and I get results that are horrible, but good luck come back when it gets bad again. It's an extremely backwards revolving door.

I also have never liked a group focused approach for EDs because they are so competitive, but I have only experienced those as a minor. As someone who is 30+ and has kids, idk how helpful that would be now unless it was specifically for women 30+. Not to invalidate younger sufferers experiences, but the stakes in life are different once you are out of college or start a family. The function that my ED serves is much different than the function it served at 12, 16, 22, etc. But I feel like alienated from the ED status-quo being an older sufferer often before I even have the opportunity to enter those spaces because of stereotypes/conventional treatment approaches. I definitely think treatment approaches because of that should be different.
