FYI There are two other entry pathways I know about, TMPRSS2 and neuropilin-1 for SARS-Cov-2. Even so I do not follow your argument, as I am missing something which you leave unstated. I enjoyed the BioRx14 article! Thanks. It does not show a pathogenicity for the mRNA-created spike protein, but I'll read it again tomorrow.
You are arguing that the actual spike protein and the synthetic genetically engineered protein from the Pfizer modified RNA are significantly different, but close enough for immunity. That is a pretty narrow slot.
You do agree that the native spike protein is inflammatory, right?
Also, I don’t think you are stating that the native virus has a pass-key like entry into any cell, as the modified RNA with the lipid coat in the Pfizer injection has.
Are you? (That would be really silly.)
Later...
