I don't see a problem to be honest, most of the supermarkets in australia sell homebrew stuff, and from my experience coopers kits are not bad. If they also stock stuff like caps etc - the stuff you often invariably run short of and need at short notice, then it'll be very useful.
And if even a small percentage of the people who try it keep it up, then there's potentially a lot of folk to a) keep our homebrew stores in business and b) change the drinking tastes of many people. Of course it will also result in an increase in antisocial behaviour, underage alcoholics and blindness, but every silver lining has a cloud eh?
