It's utterly lovely when people then agree with you, I must be important: https://news.ycombinator.com/item?id=29330953 Here's me getting 54 upvotes for some random thought I had around candid street photos being related to the idea that photographs stealing part of your soul.
Back to your actual post though. I think you're conflating people "whose jobs depend on compliance" with "having a passing bit of expertise on the subject"
If you happen to run a multi-billion dollar company that produces vaccines, then I would assume you both have expertise in vaccines and are pro-their use. In the same way the CEO of Ford would be a good person to ask about making cars (and I'll admit is unlikely to tell you to walk).
I think Gates, Fauci and MDs are a little bit different from this group - as they're outsiders who have a remit and have decided vaccines deliver on it.
I also think you're being a little disengenuous - but in the spirit of your post, I will respond in a similar fashion. I'm not an expert in most things, but I accept the life I have and desire is based upon my putting my faith in others with expertise, and this is how we've built societies for the last few millenia. I trust Ford to sell me a machine that will not kill me as I move about at my required 70 mph, in the same way I trust Pfizer to put a jab in my arm that'll lessen the chance of a virus killing me.
