Unnecessary for you and your usage, but there a lot of situations, environments, and applications where a heavier, larger vehicle is necessary. If you live rural you aren't driving a small Fiesta hatchback everywhere. If you have a large family, an SUV is a basic requirement of modern living to move the family around.

Conversely if you live in a city with tight quarters as a single person with no kids, an SUV or pickup may not be necessary at all.

There is a reason we don't dictate choice or consumption with something as necessary and basic as transportation because it isn't one size fits all. People buy what they generally need.
