I support you. Personally, after spending way too much time thinking about Bourdieu etc., I've come to believe that:

(1) The majority of worthwhile human activities have some dimension of "showing off" to them. (2) Worrying too much about showing off is best thought of as a form of neuroticism.

I mean: Marrying someone you don't like because you think they'll impress your friends or spending all your time trying to look good on Instagram is surely bad. But having a personal library is not like that!
