I probably agree that this's something better to try when you are young and don't have many responsibilities—lower trial cost.

With that said, it's still possible for a family with children, I personally do know some nomad families, but they also have bases and travel whenever they want.

And I think it's actually not about being a nomad or not , it's about taking control of your life. E.g. I don't want to be one of those people who can only travel during holidays when it is so crowded everywhere; I also don't want to need to ask for sick leave when my body doesn't feel like working, and many deeper personal preferences leading me to nomad life; However, I also live in the same place as most people and have routines because I need downtime to focus and do the work, I do adventures when I feel like to. Maybe the real difference is I'm the one to choose: where, when, how, and with whom, instead of falling into the default setting without questioning it.
