Not the OP, but my guess is &quot;nostalgia&quot;.<p>I&#x27;m sure there were people who insisted on using horse driven carriages, long after automobiles took over. &quot;It&#x27;s just the proper, cultured thing to do. And you can tip your hat to other passing carriages! The shared feeling!&quot;<p>Although note that sentimental items can have a value of their own. Cinemas could perhaps even <i>increase</i> the ticket price dramatically in that world, making it a &quot;luxury item&quot; on purpose. &quot;Tell her the depth of your feelings with a real cinema ticket&quot;. Remember diamonds?
