If a bunch of companies started setting equal salaries for remote work not dependent on location, then over a long period of time the workers with the desired talent level would migrate to areas with low cost of living and start applying for those jobs. The issue is that today the people with the desired talent level are likely to have already moved to a HCOL area because that's where the highest concentration of available work is. You have to compete with the other jobs they could take that are scaled to the HCOL area. Turns out popuplation migration is not instantaneous, spherical, or frictionless.
