I think saying a human being can be called a "person" - meaning rational agent, is also misleading. Almost no human being can live out the rest of their lives alone without becoming seriously dysfunctional, (and irrational). The rare human able to do this has terminal cancer or is very old and is about to pass away this very night and/or week at tops.
