I'm constrained in my ability to talk about particular negotiations but, to the limited extent that HNers are taking direction from my life decisions, I'd advise you to assume that my negotiations do not frequently include "I consider myself basically a commodity fungible with a few hundred people you could source today and so I guess I'll take whatever the standard offer is."
I have followed a lot of your work. But I cant agree with all of your advice. I have been earning several 100Ks of salary since many years at FANG companies, possibly more than you. The biggest leverage for me has been from having multiple offers and performing well enough in the technical interviews to get an offer at an appropriate level. Me thinking of myself as a unicorn/laborer played no part in it. I just don't see you highlight any aspect of this in your advice.
