An example of what I'm imagining would be like if markets added to US Politics or UK Politics also showed up in Politics. Further, markets added to, say, California Politics would show up in US Politics and Politics. In other words, these hierarchies would be arbitrarily deep. Another interpretation of this concept might be if the "Communities" featured on the Groups page were themselves groups that users could create and manage like any other group.

This market resolves "YES" if anything resembling this concept exists by the end of 2024. Otherwise, this market resolves "NO" instead.
