Health care in off grid community?

I am wondering if there is anyone out there living in an intentional community or off grid and what they do about health care.  I recently reviewed a few health plans and some would be free for me under the ACA (USA) but they sucked.  I didn't qualify for Medicaid although I probably will next year.  
I take prescription medicine for depression/anxiety and bipolar mood swings.  As of right now, this is not negotiable.  I have tried going off and it did not go well.  Maybe one day I will try again.  But how do we cover things that herbs cannot cover?  If you fall off a roof, get in a bad car accident, get maimed by a bull or dog, etc.  Cancer, diabetes, COPD.  Surely there are conditions and situations where home medicine and herbal remedies do not suffice and doctors and hospitals must come into play.  What are people out there doing for health care/health insurance?  

We discussed this at the ic I lived at shortly.  There was talk of a group plan that would be paid for with funds from the farmers market.  Idk how this stuff works, but I suppose if it helped, the owner of the ic could register as a business and for the sake of paperwork, purchase a group plan for the residents (employees).  Again, not sure how employer covered insurance works.  

I think this is a very important question.  I get the impression a lot of people plan to stay healthy or die conveniently quickly, like in the "good old days."  They don't tend to think about the good old days when many people lived as invalids or cripples for years.

My family would have been destitute without health insurance.  Aside from several medical disasters in the family, both my sister and I have bipolar and depend on pharmaceuticals.

Please don't try going off your meds again.  I've tried several times and it never works out.
