Did you forget your (/sarcasm)tag? The "children" can get it now on practically any street corner. If legalized, taxed and controlled like hard liquor is (at least in Texas, where hard liquor is sold only in liquor stores and you have to be 21 to walk in the door), it would not be any more available to kids than it is now, possibly even less available. Sure, you will still have irresponsible adults purchasing it for resale to minors, but you have that problem now, which negates that argument.
