I really think that's the crux of the matter: these things are all personal preferences that stem from a deeply emotional place, and emotion rarely makes sense according to the laws of logic.

For example: my parents have a truck, a van, and an SUV. Do they need all of those vehicles? No. Do they get used all the time? Yes: my parents are both avid gardeners, they generously lend their vehicles to those who happen to need a truck or a van for the day, and I have several younger siblings who occupy them the rest of the time.

And even if they didn't, I could well see my dad still owning a truck purely for the convenience of being able to drive to the local garden center and pick up a load of mulch on a whim - even if in practice that happened twice a year.

Emotions are strange things.
