Earlier quoted context omitted.
You seem to assume SF salaries will be offered in places that are also super cheap? Do you expect founders and investors to ignore the cost of living reality in Nowheresville just cause?
Why on earth would the value someone added to a company have anything to do with the cost of living where they live? Either you support remote or you don't but I would not expect different remote salaries based on where that remote employee lives. I know some companies do this, but I can't imagine it's a practice that will continue once remote work becomes the norm as it makes little sense.
Most companies would stop hiring remote if they had to pay SF salaries - that's just the fact.
