I can't entirely tell whether you're missing this or simply beating around the edges of it, but: The focus on openness for mental health, to the exclusion of all other solutions, is about productivity and hierarchies. Employers and managers aren't ready for their employees to take care of their mental health. That would often involve paying for them to have better access mental health care. That would often involve them having relatively sudden and/or extended absences (followed by greatly improved health and much better productivity!) and they're not going to pay people for extended breaks. It would often involve adjustments to the way people perform work and interact with management. It would likely involve removing a lot of abusive people from management roles, since they are likely causing a lot of these mental health issues. People with authority are not prepared for a system that accommodates mental health issues in a serious way.
