Might want to check out your source. Look at the vid again ... he has a sign on the glass reading:
That's the going rate in Colorado shops, as well."Fast & Vast" (I'm assuming that's a strain he's selling)
2 grams $50
He also says $10,000/lb is his "break even price" (paraphrasing). So 448 grams (1 pound) x $25/gr gets him $11,200. Close.
Your claim it's going for $75 per gram doesn't add up.
