That's fine and dandy for experienced PC users like you and me but what about regular people? Housewives, pensioners, working people who want to use a browser but don't have much time to invest in learning its intricacies.

I think you are vastly over-stating the cross-section of the population that both has no idea what a browser extension is, yet knows about RSS and cares about using it.

That was my point. If they don't have that functionality in the browser they certainly won't go looking for it. If it's built-in there are ways to make the user aware of it (startup tips, random info pop-ups or even suggestions from more advanced users - "did you know you could do X very easily?").

I agree with you. I am very careful about which extensions I install because I dislike clutter (one of the many beauties of Chrome is it's simplicity). Also, I do not want to end up having extensions that might disappear. If the extension functionality were part of the browser, that would not be a problem.

I am sure those who used Firefox with all addons/plugins would love extensions. For me, extensions are to 'extend' the browser functionality, not to fill-in for the lack of functionality the browser should have.
