Before the COVID-19 crisis, cruise ships provided private medical services to over 20 million people a year, many of them elderly, and their routes remained within helicopter distance from land hospitals. Oil rig workers often must remain in more remote places performing more dangerous work than seasteads will ever have to face, and they are served by telesurgery and telediagnosis in emergencies. Many medical entrepreneurs want seasteads precisely in order to offer patients better, cheaper services than they can acquire on land. As the seasteading population expands, entrepreneurs may establish a medical practice similar to what is available on cruise ships. Hospitals, doctors’ offices and clinics will be available at the host nation for early Seasteads in protected waters.
