This is just my opinion :) but, clicking in the address bar in order to type a URL seems pretty inefficient. Why not activate the address bar with the keyboard, which you will need to use to type the URL anyway?
It's similar to typing a URL in the address bar and instead of typing Enter to navigate, you grab the mouse and click the little 'go' arrow on the right.
99% of people who use web browsers don't use shortcuts like ctrl-L, they just use the mouse to click.
It's kind of like asking why people don't just run irssi on ec2 if they don't want to be disconnected from IRC when they close their laptop: it just fixes it for a few nerds, not for anyone else.
I think the comparison is a bit exaggerated. People generally know how to use ctrl+c and ctrl+v. Keyboard shortcuts aren't that nerdy, some of them are explained in the Windows 95 User Guide.
Meanwhile UI consistency is useful for everyone, not just nerds. I think optimising software for some minimal set of lowest-common-denominator use cases like this is a slippery slope.
