You're not wrong. ideally we van/RV people would love to have a house AND a travel option, but realistically money prevents most people from having everything they want,

so when it comes to choosing a lifestyle whether in a static location or freedom to travel, most people have to choose one or the other.

Life is difficult and full of challenges no matter what you do, so you might as well go all in on the one thing you'd prefer most, and just deal with all the pros & cons just like everything else in life.

And hey there are tons of sad confused mentally ill people who live in houses too. maybe the ones living in cars would have felt the same way living in a house, but they're saving hella money by not having to pay rent or mortgage. And money saved up over time, you know what that becomes? Money can indeed buy happiness.
