Anecdotally I see a strong clustering. I have friends with a ton of books, and their other friends also heavily liking books and physical goods (CDs, cards etc.) in general. My other friends tend to have basically nothing in terms of physical books, music, movies. I’d wager it depends on how people see physical goods in general: is it an asset or a liability ? And the “minimalist” switch might become more and more attractive when people prefer to rent instead of going into debt.
