Conservatorship in my state is separate from an estate. Regardless, it doesn't mean house arrest. I could have done what you suggest when my daughter was active in her addiction, but nothing would have stopped her from walking out the door. She would not have met the legal criteria for becoming a ward of the state, and in a lock down facility.
How about sharing your personal story with codependency and addiction, and what you're doing to overcome it? The guilt manipulation from you indicates you haven't overcome it yet.
