I wonder if there's coordinate potential with seasteading? Astronauts are gonna want all sorts of goods and services upon landing I imagine. Having someone stationed nearby will mean swifter pickup of equipment and astronauts. And if there's someone stationed nearby they'll want goods and services as well.
I don't think astronauts would land on the droneship, as that's just for the first stage. When the Crew Dragon lands, it would be coming in from orbit, so I imagine they would just target the landing platform at the Cape as part of their de-orbiting plan.
That being said, would you want to be in the nearby path of the rockets if they were going to be ditched?
