My point is that any degree of "thing" can be enough if you accept its implications. So for example when you go on your family vacation, you make choices about what to take and what to leave. If your two year old daughter asks last minute if she can bring her scooter (and helmet), the answer might be "sorry honey no room" whereas with a larger car you could say "sure, toss it in." Or the grownup version of that, I tossed in my inflatable paddle-board, paddle, lifejackets and pump as a last minute decision for our last vacation "just in case" we want to get on the water before the kayak rental place opens up (ended up using it.) Again, the paddle-board or scooter are totally non essential - if I had a smaller car I wouldn't even consider bringing them at all and that would be totally fine, but it's nice that I can.
BTW, we got our SUV when our 1st kid was born, it was a larger car than I thought we needed but was still kinda helpful. By now we have 3 kids and the fact that "how are we gonna fit them and their stuff" isn't one of the many things we have to deal with as parents is very nice.
Again, if I couldn't afford it or was very anti-big-car, I'd find a way to make do with a smaller vehicle but it's nice to make the other choice and that's why many many many people do.
Or for example I had to point out to my dad that his neighbor open carries. Like my dad is intellectually aware of the 2nd amendment but it didn't fit in his brain that people could actually exercise a freedom so his eyes were literally blind to it (obviously I drove him to the gun shop that evening)
