Zero oxidation=zero aging. Why TF would I put up a beer for a few years for it to stay exactly the same? Read the book 'to cork or not to cork', a treatise on the quest to develop a synthetic wine closure that permits the graceful aging of wine that natural cork does, without the unpredictable quality issues of a closure made from natural materials.
A perfectly hermetic seal would create a Schrödinger's beer, simultaneously alive and dead. Since one can enjoy fresh beer whenever one chooses, what intrinsic value is there in preserving it in its fresh, unaged state? Imagine meeting a wizened old man with the emotional maturity of a child? There is value in preserving something to be sure, but to erase the passage of time is wasteful of the one truly unrenewable resource.
