Users never returning has an effect on bottom line. So you can make the argument from that position. Whether users return, and how that hurts your business, depends very much on your site and your users. I will disagree about UX not being about bottom line though (in the usual context of a for-profit company of course). In a common setting, whoever pays developers and designers are doing so as an investment that they think will be profitable. If you can cut costs without hurting (long term) revenue by cheaping out on UX then of course you should (!). But often the idea is good UX will drive revenue...
