You mean the post where he said that those people choosing to spend that money is "perfectly fine"?
The post where he said: "There's nothing wrong with liking series/dig discs, and supporting your favorite players, or getting into special runs, or other limited stuff, or building a bag exclusively of this or that brand." and then said "Like so much else in this wonderful country of ours, the choice is yours."?
He's not whining about people spending money on discs, special stamps, or anything else. He's simply explaining that you don't have to. I do not see any complaints from him about people spending excessive money on something. I see him acknowledging that they have every right to do that, while making it clear that they do not have to.
