Default more thoughts on PET versus glass permeability

Following from a previous thread on PET versus glass, I observe that
the concensus seems on the whole to be thus:

Glass is better than PET for long term storage, because PET is felt to
be more permeable to oxygen than PET.

If that sums things up correctly, I would like to ask about the
following consideration:

Is it not the case that rubber is hundreds of times more permeable than
either, and thus the degree to which a long-term storage wine oxidizes
in the carboy is really not significantly altered by the vessel, since
most of the permeation of O2 is going to occur through the rubber?


Your thoughts?
