Here's another guy I met. Top 3 C&V bike collection in Taiwan, which mean something since they are the bike manufacturing capital of the world. Don't know how old he is, but I'm certain he's under 35. His best friend in Taipei (has 400 bikes, mostly all high end), is his age too.

These people shouldn't exist if you go by your logic, but they do. So maybe your logic is wrong.
