Chemistry is the causality, not the fact that you started measuring it. Also, those CFC were predominantly in refrigeration units, which were not common in the 1920's.
Your argument is closer to: "Germ Theory is a scam made up by the medical industry because diseases existed prior to it, and we don't know that any of those were caused by viruses or bacteria."
My argument is the line I quoted from you is, "Microbes were not known to exist prior to [event that preceded the intention of the microscope]" and a lame way of implying a relation when you know it's a non-sequitur.
