The way I saw and see the matter is this: caregivers cannot run a for-profit business because that would entail regulation, inspection, taxes etc. It's better this way without any of those kinds of oversight. I like that patients have all three options: for-profit retail, non-profit small growers, or self production. I also like the fact that caregivers can grow without ever seeing the face of a DPHE inspector, a cop, or a revenoor. That seems to me to be the intent of A20. (although I'm glad we also allow dispensaries!)
