That's true, but kerb impacts are pretty common when cycling a lot in traffic, especially the rear (though, intuitively I would assume that that detensions the spokes rather than that it tensions them). For the front not so much, you can usually pull up the front in time. But on a bike heavy with shopping you may not always have that luxury.

I think I understand where you are coming from: competition MTB is a pretty interesting niche and it allows you to really max out on the bike for those conditions. But it makes me wonder how long such a very tight setup would last in everyday use over 10K km / year or so. Because that's my application, I've never done any MTB / offroading and at a guess stuff breaks and gets replaced far more frequently in that setting.
