You can, as some explained but the problem is mostly the UI.
Apple has always been a bit crazy about removing anything that could appear complex to its user, because it thinks they are fools and idiotic.
So, you have to use a stupid shortcut instead of having generally available UI.
The funny thing is that they still have an option to display path as breadcrumbs, so you basically get to display the same thing without the functionality.
There are some things I really like in the Finder (like Miller Columns) there are a lot of stupid decisions (that have increased over the years) in an attempt to make it "simpler".
But it ends up being mostly good for looks and a pain in the ass for actually getting shit done.
I think Apple has drifted too much to the "common man" (at least the representation they have of it) because of the iPhone. This has made them try to "simplify" everything when their niche market previously was "power users" (the only ones crazy enough to spend that much on their computers).
It's a bad bet because the "common man" just goes with the flow and buy what's popular, looks good and give status. They can go from hero to zero very fast, just like Nokia did, I think they are too arrogant to realize that.
