For some values of "you": a tiny minority of noble people and well-off merchants. Chances overwhelmingly were you'd be born, live and die within the same 5 mile radius.
Did you read the story? The Noregian Nicolai was not well off. Like a large part of the Norewgian population, then and later he started as a sailor. Many Norwegians would go to the seas from 15 years old. My great grand father was from a poor working class family like most of my sncestors. He worked at a quarry in Norway with a sledge hammer. Nothing privileged about it. Yet he also signed up as a sailor and worked all over the world. Layed railroad in the wild west and worked many places in south america like this guy. And like this story my family thought he was dead as he was away so long.
Did you read the comment I was replying to? Any attempt of organized travel was enormous and expensive undertaking, the lack of bureaucracy and effective border controls hardly made up for it.
But sure, you could become a sailor, or get conscripted to soldiers, or even sold into slavery to a distant land. Doubt though that was the kind of travel the GP alluded to.
