     'Can't' and 'dont't' are different things...   
      
     In any event, if we get to the point of launching a manned   
   interstellar mission at any reasonable speed, that will obviously not be   
   true. What makes for an interstellar slowboat, is still fast   
   transportation *within* a solar system.   
      
     And it seems to me that your argument, if anything, also works against   
   any proposal to send habitable modules, or anything else, *50 years*   
   ahead of a mission going only as far as Mars.
