Yep.
My legal four in Oregon, grown out doors cost me about 50 dollars to grow, most of that was in seeds. Out the back end popped 7 pounds of pretty good weed perhaps not top shelf but good. At my current rate of consumption seven pounds is about 63 years-worth. I like growing, so another four will go in my garden next year. Oregon allows gifting so, friends, family and friends of friends are all happy. Why buy it when you can get good weed for free or nearly so. Also, no pesticides, no mold, nothing to worry about. People gift me, I gift them and so, plenty of variety too.
Boutique tippy-top top shelf weed will probably always be pricey. Everybody else will grow fire at fire-sale prices or else they won't even be able to sell it. The growers that make it will know how to efficiently produce large quantity of fire. As you say, not going to happen tomorrow but see it coming soon.
