You championed the "Cheap, legal weed for all!" mantra and got it legalized. Okay, now it's legal. And cheap. And suddendly your operation, which you built around an economy driven by restricted supply, is failing. You didn't listen to your own words. It never occured to you that "legalized" is synonymous with "taxed and regulated". It's also synonymous with "industrialized", which invariably results in reduced consumer prices as economies of scale take hold and demand begins to outstrip supply.
In short, you got what you wanted. Quit whining and deal with it like the rest of us have to.
