This analogy would work better if organ transplants, prosthetics, etc. weren't a real thing and the medically right answer in many cases. If your hip needs replacement, no amount of eating healthier will cause it to no longer need replacement. There are, of course, many situations where divorce is not the right answer for that situation, just like there are many situations for which a hip replacement is not the right answer. But it is within the set of potential right answers across all situations. There's no sense in trying to replace what is easily repairable, and there's also no sense in spending your life trying to repair what needs to be replaced. And it's totally possible to go through life where neither you nor anyone you know ought to get a divorce - just like it's totally possible to go through life knowing nobody who needs a hip replacement, but that is hardly evidence that the procedure is the wrong answer for everyone!
