I mean it's a pretty cynical view on the Magic design process. I think that Magic would be better served either supporting limited (and not having GRBS mythics and rares), or supporting constructed (a la the living card game design). The thing is the LCG model doesn't let people open packs to gamble for the mythic you need four of to go in the deck you want to build, it just lets you build decks, so it sells less product. If you only support limited, your kitchen table magic doesn't change much (cf: EDH is an abomniation being a seriously serious casual format), the quality of your limited goes up, as your value and/or archetype uncommons become the most powerful things around, and you end up selling more product as everything you do (except kitchen table magic) requires opening product (except, you know, cube). The problem is you lose out on the serious constructed players, or rather the singles traders, buying mass amounts of product to crack to get at the crunchy four-of mythics.
There's a discussion on that forum about the recent fakes, and the cost of singles and such. I did some really rough maths with a bunch of assumptions, and came to the conclusion that to support a single standard deck all season, you need to spend $200-$300 on singles per set release (depending on your deck of course, but I made some assumptions as to meta shifts that require you to completely swap deck). That's including keeping staples. Magic is expensive, yo.
