I think the better question Art is where does your spouse allow you to put pins. For us on the single side, its really preference, and if we're voting here, its pretty clear if there were room in the bathroom I'd have one in there too!
Good luck. Sounds like a mess. My advice, let her pick which ones stay in plain view and hope you can keep the rest out of sight and out of mind. If I had to guess the rub and the reasons are aesthetic vs practical.
