This is a fantastic way to respond to it. But I do fear if it's a slightly emotional response and not a more assuring one. It's probably the best way to address the elephant in the room though, aside from having a kick-ass product that addresses their pain points.
In my limited experience selling things, sales are all about emotion. Yes, there are a few actual deal-breakers, but things like a willingness to learn new things or adjust their workflow or deal with a mildly suboptimal workaround depend entirely on emotion. And the same suboptimality or problem in the hands of a person who wants a deal to work vs someone who doesn't swings in two different directions entirely based on the potential customer's emotions.
