Nomads, by definition, don’t meaningfully contribute to a community. They don’t create deep relationships, families, or traditions. Instead, they bring outside perceptions and traditions that may either invigorate or destroy the community they are visiting.
Is it good for the community’s economy, probably. Is it good for anything else? Probably not unless the culture is at least adjacent to one you’ve lived in before. (IOW, if you come from one strong religious community to another one, or an artistic community to another one, you would be able to recognize what you’re experiencing and fit into your worldview; thus being able to more easily meaningfully contribute to the community)
