True, enough ... one must consider both the kinetic and thermodynamic requirements for existence, but I was thinking that the system was perhaps at equilibrium by now.  Still, it was careless of me to use non-existence to argue for either the absense of cause or presence of impossibility.  I am still waiting to get a straight flush in 5-card draw.
