Just a few points to make.
1. Black Market =/= Cartel market: black markets consist of everything traded without govt oversights/collections. Could be a cartel guy, could be your neighbors 50 year hobby of growing exceptional sensimilla. Black markets are free markets.
2. Legal weed and black market weed can both suffer from the same problems, over supply driving prices down, a new pest that ruins quality of crops, grower errors, etc. Black market weed is lower risk with regards to bankruptcy and state seizures compared to legal weed in most states.
The burden of the white market allows only a few players to play and lower quality products at heightened prices with little margin. You're only going to find the McDonalds of Annalise succeeding, low quality products (but consistent) and churn and burn mentality.
Sucks. Best to find yourself a quality grower and help fund him directly.
What bitcoin’s detractors don’t understand is monetary economics, computer science, software engineering, network protocols, and electrical systems.
It ain't much, but it's honest Proof of Work.
