There went the loserdopian argument that legalization is the last thing that drug dealers would want.
Not at all. You're entirely missing the point. Legalization is the last thing the *illegal dealers* want (i.e. the drug cartels, organized crime, Joe the local pusher, etc.), because if Walgreens or liquor stores could carry pot legally, customers would buy from there, and not risk getting their pot from the illegal sources. (How many people do you know who still buy their booze from illegal bootleggers?)
That's still true, and it's hardly invalidated by the fact that an activist has chosen to sell seeds in order to challenge the laws. He's not doing it for the money, like the drug cartels are, he's doing it because ultimately he wants to be a (legal) *consumer*, not a dealer.
