Lanc, Hurricane and Spitfire are much, much simpler aircraft than the Vulcan, and quite similar in construction and use to the many thousands of light aircraft dotted all over the world. And training a whole crew of people to maintain a single aircraft of this complexity, used only for displays, would be totally impractical and cost prohibitive.
Both issues ignore the second problem - they don't know where to look for problems. Where I work, we have a full aircraft rig simulating flight on a full airframe of a Tucano. That Tucano is kept ahead of the fleet in "flight hours," so that cracks, fatigue damage, etc can be found on it rather than a real, flying aircraft. If you have an aircraft as complex as the Vulcan, where the only remaining flying example is as far ahead of the fleet as this, you are likely to face very serious issues sooner rather than later.
As gutted as I am to see it going (and being in NI, as unlikely as I am to see it again), I completely understand the reasons behind why it is being retired.
