Naturism is fundamentally a social movement. It challenges the "legacy of taboo" surrounding nakedness by separating nudity from sexuality. By interacting with others in a state of nature, practitioners often find a sense of community that is harder to achieve in a world of high-fashion filters and social hierarchies.
Body positivity is a difficult, often lonely journey when practiced alone in a clothed world. Naturism offers a community, an environment, and a practice that accelerates that journey. It is not a quick fix for deep-seated body hatred, but for many, it is the most effective medicine.
