2013-2014 were disastrous years for Morrissey, tour-wise (relatively speaking, of course, because there were certainly plentiful cancellations before and after that time period). The topic of tour insurance came up often. Yet, he never seems to have much trouble getting a tour scheduled, so my guess is he'll find a way to continue on if he wants to.
It all becomes a bit of a joke, though, doesn't it? Never knowing for sure until the lights dim if he's actually going to turn up? And even if he does make it onstage, there is a 3% chance he'll walk off after a few songs for some reason or another.
Put simply, this cancellation nonsense is strictly a Morrissey phenomenon. It does not happen anywhere near the frequency with any other band/artist. Prove me wrong. Show me the data. Because all you have to do is look in the Tour section of this very website to see the long and predictable history of compete Morrissey tours crashing and burning as well as onesy-twosy cancellations with absurd explanations given.
