No, I think you're being incredibly naive if you think the outcome you imagine would necessarily come to fruition without Google being a "monopoly" (however you define it). It didn't happen for Microsoft (Chrome is an angel compared to Edge), and nobody has managed to create comparable solutions for so many other products Google offers that have nothing to do with the browser or search.
Google was also caught giving special treatment to google-related domains in chrome, and had to revert the advantages around cookies that they gave to themselves.
It rather sounds like a great marketing opportunity for anyone trying to compete with Chrome, whether they keep the v2 or just implement ad-blocking themselves.
But in reality it just doesn't work out that way, the negatives from abusing their monopoly can be overshadowed by the power of the monopoly itself, for example Google promoting Chrome every time you you gmail, google search, or youtube. Or making their services not work well in non-Chrome browsers.
Or in the case of microsoft, their monopolistic behavior is overshadowed by the fact that too much important software only works on Windows. It's a tale as old as tech.
Google has been the one pushing for getting rid of the v2 manifest for browsers extensions, which just so happens to seriously nerf ad blockers. Because so many browsers are forks of Chromium v2 will disappear from a majority of browsers. Meanwhile if you try to use a non-Chrome browser like Firefox a lot of websites are buggy and outright don't work. Opening images in issues broke in GitHub for firefox a year ago and they still haven't fixed it.
You are being *very* naive if you think that Google having this sort of monopolistic power over the web does not hurt consumers.
