It's just marketing. The last kind of disc a noob will buy is a mid-range. All the marks are looking for the magic distance driver and the magic putter, not the magic mid-range. If you're selling discs out of the trunk all you want to stock are the high speed over-stable discs that are totally inappropriate for the skills of your average chucker, because that's all they want. But when they get a little better they'll want a putter. And eventually they'll want to try every putter that ever was, convinced that it is the disc, not the thrower, that is lacking.
