Firstly, DECRIMINALIZATION maintains it's legal status (ie: illegal) but removes or reduces the penalties associated with it- most specifically jail time for a first offense. You will not be able to grow weed in your front yard or smoke openly or freely with your friends. You would possibly receive a fine or some other sanction. Repeated offenses could still result in jail time. And typically that would only refer to simple possession- not cultivation. Certainly you will have the illegal product taken from you.
LEGALIZATION makes it, um, LEGAL. No crime, no fine, no penalty.
MMJ legalization and MJ legalization are 2 completely different topics with different political motivations behind each.
As far as the tax goes, some of the numbers I've heard go much higher than $50.00 / ounce.
In a free market economy, the purveyors of consistent and quality product are the one's that succeed. That goes for MJ as it does for anything. So yes, there will be mass producers that produce huge quantities of consistently average MJ in a legal free market for MJ. There would also be the micro or boutique growers that produce high quality, consistently good product. Do you buy and ounce for $150 or do you pay $300? It's up to you and what you can afford.
Taxes are a necessary evil. I wonder if any of the people who have commented on this thread about the "government" or whatever screwing things up, and making comments about not paying to grow my own herb, blah, blah, blah, have ever received or currently receive some sort of assistance or state sanctioned assistance (ie: disability). If so, you ought to be ashamed of your comments. Where do you think that money comes from? If you lose your job, should the government help you out? And if you think the small amount your employer pays in unemployment taxes covers what you get, you are sadly mistaken.
Unless you are profiting from the growing of MJ as an illegal activity, you should only hope for legalization.

Just my .02. Don't mean to offend but when I read some of these posts, I just don't get it.
