I have to say that I agree with the sentiment that wheels really shouldn't be going out of true. None of the wheels I've built have.
But of course there's the element of specs. In order for a wheel to remain true it needs to be specced correctly for tge rider and use case. You can't put a 16/20 spoke superlight aluminum wheelset on a DH rig for a 120kg rider for a weekend at whistler and expect it to stay true. However give that same rider a 24/28 spoke high profile carbon wheelset for general road riding and chances are that the wheelset will not require truing. If said wheelset has veen built correctly.
There's of course some oversimplification as spoke choice etc. play a role but I thought to keep things simple.
