I posted this idea back in 2009 or 2010, during the Obamacare debate. There are undoubtedly a lot of old cruise ships and naval hospital ships that could be used. I would add helicopter ambulances to the coverage for serious injuries, and ferry rides for those that are not. I also predicted that the fascists in charge of the US would eventually try to sink these ships or prosecute citizens who use them. Unless they are members of Congress.
If brand-new cruise ships can be constructed at several a year, can’t you see the rationale for these being built from the keel up as well?
