High school chemistry was a long time ago - and I hated that class, anyway, but isn't it that at the triple point you must still change one factor in order to attain one of the actual states?
I don't think so:
"The single combination of pressure and temperature at which pure water, pure ice, and pure water vapour can coexist in a stable equilibrium occurs at exactly 273.16 kelvins (0.01 °C) and a pressure of 611.73 pascals (ca. 6.1173 millibars, 0.0060373057 atm). At that point, it is possible to change all of the substance to ice, water, or vapor by making infinitesimally small changes in pressure and temperature."
Its all 3 at the same time - sorry. Otherwise I liked your argument.
