Most of my vintage stuff now hangs on the wall, and I spend my riding time on either my Cyclops, which I upgraded to New School components, or my brand spanking new Trek Crossrip. I see aboslutely no problem with someone wanting to hang his, or her, bike on the wall and then appreciate the aesthetics of the machine.
I might even hang the made in China Trek on the wall and just look at it, now and again. I am impressed with the quality of the bicycle's construction, the overall appearance and more than impressed with the ride quality it offers.
I do like the ride quality of the older bikes, but I do not, necessarily, like the poor down tube shifting and the poor stopping capabilities. I make those comments as comparisons to riding newer school stuff that jut plain works better for me.
