Dave, the systems you describe are actually entropic. They create order locally, but at the expense of creating disorder in the universe. There are no exceptions to the second principle of thermodynamics, as far as know.

As for demarcation being complicated, yes, I wrote a couple of books about it: https://press.uchicago.edu/ucp/books/book/chicago/N/bo28300772.html and http://www.press.uchicago.edu/ucp/books/book/chicago/P/bo15996988.html
