Presumably, humans will resort to asteroid mining at some point. They might use hard nanotech for that purpose. If they aren’t careful in how they do so, a gray goo might end up taking over any body in the solar system not too warm to support it.
Intentionally designed replicators with thermal shields and heat pumps could be more aggressive. However they would probably tend to be larger and hence less difficult to locate and destroy.
