Even if you think you own it, you don’t own it.

Is that a solution to the nomadism? If you rent, you both technically and practically don't own it. If you buy the house, at least you own it in some sort of spectrum of legislative and burocratic scenarios. That's not ideal, but far fron the worst case scenario.
You don't fight the "you'll own nothing and you'll be happy" by refusing to own stuff...you fight it by enforcing your ownership whenever challenged.
