As far as I know, it is possible to have the entry "ohne festen Wohnsitz"(without a permanent residence) instead of a mailing address in a German passport and he's legally not allowed to use his parents address, if he's not there for at least 183 days a year.

But I don't really understand how this small legal detail would change the whole character of his life experience, in any case. No matter what is written in his passport, he spends the whole year in a train.

Because there are real nomads, people without any address that run into all sorts of legal difficulties, difficulties that are belittled when people write about how easy it is to live on a train 24/7. Some are "homeless" others are from cultural groups that roam. And a large number are children in government care who then must transition to adult life sometimes without the convenience of a fixed mailing address. Our systems of government and assistance are still based on legal residency at a particular point on the map. Despite all the stories about mobile professionals working wherever the please, this is a privilege enjoyed by those who retain fixed support infrastructures to which can return as needed.

Look at the "Van life" trend. The people are forced to live in their cars/vans really do not appreciate those who glamorize it. It is not an easy thing.

Anyone with two brain cells can tell the difference between a homeless person and an adventurer. Pretty much anything people do to challenge themselves sucks for someone who's stuck doing it without a choice.

There are services/agents that act as your address. Not everyone chooses to do this but what you describe is solvable.
