[Homeroast] Using CO2 to preserve freshness?

Your arguments beg credulity in the following respects, sir:

   - The return on effort of purging is great, although you assume purging
   is the optimal procedure. There is no necessity of excluding every O2
   molecule from the vicinity of the HC coffee beans, Some were already engaged
   in assignation with the beans and oils of your coffee before purging.

          The effect of the 20% atmospheric concentration of O2 molecules
proportionally reduces O2 by the purge, however ineffective it may be.
Better than no reduction at all.

   - The O2 displacement by the more dense CO2 molecules in a closed
   environment further reduces oxidation, unless the jar has built-in jet
   streams or meteorological convection currents like the planet has.  Same
   magic runs windmills...
