I'll state up front that I do not aspire to a small wardrobe. It's extremely impractical for me (lifestyle and climate requiring a wide variety) as well as not my preference (I get bored). Of course, I can definitely afford to size down, if only to get less "noise" and make happier outfits. The Joshua Becker link was interesting.

The overall approach is good advice, particularly the mental shifts and resolves. I LOVE color, so wearing fewer is a total non-starter for me. But that's preference, and it's a good idea for people who don't care so much.

The actions are problematic. Get rid of almost everything. Buy nothing. (Meanwhile wearing out the few clothes left.) Waiting slooowly (while existing clothes continue to wear out) for enough money to buy the Quality Items from then on.

Is such a purge necessary before quitting shopping? Surely it would make more sense to do the initial clear-out, then stop shopping and SYC, before another stricter clean. Must you hack your budget before buying only expensive items? That's asking a lot of anyone's discipline. And what about wardrobe holes that emerge in the cleaning process? I feel there's a critical mass point in the minimal wardrobe where you've got sufficient happy, quality clothing (of course the hunt always continues); but that critical mass is going to take years to reach with this approach.

I may be taking this too literally, and I know I read with a raised eyebrow. C.S. Lewis once wrote that people who hate mystery books should not write reviews of mystery books, and I'm almost in that position! But I don't hate small closets or few clothes; I just think I see some logical difficulties. Maybe it's just a topic hard to describe in a short article.
