I definately want weed to be legal, even if it is subject to the same laws of capitalism as everything else on the PLANET. I just have my priorities, and not killing people is one of them. lol. And yea, if walmart gets into the business im sure that small time growers will be able to grow higher quality bud, so there will still be a market for it (i THINK) but now that i think about it, cannabis comes in different textures, flavours, smokes, effects... theyre illegal cigarettes, i suppose if they can grow bulk quality tobacco they can probably do it with cannabis.
But my point was that even if walmart or target or whoever dominates the market, im sure there will be private growers still just like with other crops. But just because you have an apple tree doesnt mean you can sell apples for a living, it wouldnt even be worth the gas to the store or the drive to your home. The only reason people would go to small time sellers is Quality or there are no other available markets. And we all know that not everyone can grow quality, in fact, few people grow that danky dank thats like 70-80 bucks an 8th. And if you think that pot yeild is so big that it would be profitable, grow some grapes and see how much you make off that. then try growing grapes when 1000s of people in your same town are growing grapes and all competeting with you.
When pot becomes legal, id bet 50-90% growers stop growing, and id say of the 10% who continue to grow, only 1 percent of them will be doing it for profit. Most will do it for personal consumption.
