That just sounds like a simple free market to me -- what so many esp. in the US believe to be the best invention since sliced bread.
With a commodity like weed (that essentially costs nothing to produce), profits will only be had for mass producers. It's not a "race to the bottom" in my eyes, it's simply a market economy at work.
All these limits that Aaron mentioned there (canopy, fees, wtf-taxes, etc.) are just distracting from the fact that weed is actually WEED, and not difficult to produce, and it should not cost more than tomatoes (which are a lot harder to produce and need to be kept fresh etc.).
@xtsho Has said it on page 1, and I agree: the stuff is legal now (in Canada), get fucking used to the fact that its intrinsic value is not high enough to run a cottage business growing weed.
Germany (where I live), is very likely to go fully legal in this electoral term (my guess is in 1-2 years); I'm expecting the same development as in Canada, no matter if home growing will be allowed or not.
