Interesting point of view. I like cycling too, and joke about getting new bikes. But a new bike a year? That does seem excessive, unless he’s very well-off.
I have some bike jerseys but I usually wear running shirts on training rides and bike commutes, not Lycra. As for the shorts, I wear thinner tri shorts, mostly because road bike shorts feel like adult diapers to me. I’ve learned from experience that some sort of bike short is almost necessary when riding for more than 10 minutes or so, because of chafing issues.
The other stuff? Well, he doesn’t really need them to ride and train. Even for racing, some of those items only help if you are really fast and you are competitive in races. I hope he doesn’t bankrupt himself or drive away his wife.
