I get what you're saying, but as an employer, the "non negotiable" and inflexible attitude is a point-blank no for me. Your OS contributions (caveat: spent 2 minutes looking) are hardly much (lists on github are not 'valuable programming', to me it's just content marketing that may as well be on a blog) compared to people asking for 1/2 to 2/3 of your proposed salary, who have core contribs, manage production-deployed packages/code that are in frequent use etc.
Your mileage may vary, so best of luck. But that's my perspective, as an employer, looking for remote devs. The competition is actually pretty high, and you can get awesome candidates that might earn $120-160k a year when working in the valley for $80-120k due to the lower costs they can incur ('valley tax') and the flexibility you offer as a remote employer.
Don't get me wrong, I know the value of a high-priced consultant (am/was one) to fix an emergency. But you're not asking people to deliver you an emergency, you're asking for a job. And to deliver in an emergency, you need a hell of a lot more credibility and slickness, which your post suggest you don't have.
* might be one, might be more. Depends on who applies and what it looks like.
