Not really, my motivation to accept a job at GitLab didn't come from how much I could make relative to everyone else in the company, it came from how I could be doing the same work I was doing for a local company but from home. Salaries aren't the only thing that make one company more appealing than another.
It's not about salary, its about fairness. This is the kind of thinking that leads to the pay gap between genders -- because women are willing to accept less pay for the same work because "it's good enough and I don't want to cause trouble". It might very well be good enough, but it certainly isn't fair. Trouble needs to be caused when unfairness is involved.
As a woman myself, I don't see this as a slippery-slope argument like you're implying. The gender pay gap is very complicated, and IMO not at all the same as a company saying "we want to offer salaries that compete with your local companies, and then also offer these other benefits like working from home" vs "we want anyone within the company to make the same amount regardless of where they live".
The gender pay gap is a whole separate matter that I'd prefer not to get into because, tbh, talking about it in tech-spheres that are still male-dominated is intimidating. I guess all I can say beyond this is that if you're ethically against these practices then I support you voicing that, and while I can offer differing opinions, I still think you're within your right to openly disagree.
