Defaults are not the same thing as a lack of ability to style
something. In fact, some UAs may actually use stylesheets for the defaults.

Not necessarily, and you're assuming that the method of navigations
the webmaster would want to use is entirely supported by the browser.

Something like that may actually lead to heavier use of <link> for
navigation. Would that allow background images as well? Perhaps icons?

Okay, there's a difference between saying "I don't like this one
thing they did with Firefox" and "Firefox sucks". Let's not start
arguments about which browser is better. It only undermines what we're
trying to do here. Also, I recall indicating that I was speaking off topic.

According to what you said before, we're talking about a bar with a
fixed, largely unstyled UI that is always visible regardless of the
contents web page. That sounds like browser UI to me.

An <a href> element may not even show up in a web page, and it
logically follows that if that's the case, you should see hyperlinks
created by them. Similarly, if <link> elements that apply to buttons in
a site navigations bar are not present, the user should not be forced to
have a site navigations bar present. Furthermore, <a> elements are
common on the web. The use of <link> for navigation is not, so most of
the time the site navigations bar would go unused.

From the HTML 4.01 spec:
"Although LINK has no content, it conveys relationship information
that may be rendered by user agents in a variety of ways (e.g., a
tool-bar with a drop-down menu of links)."
Notice the use of the word "may". That means that rendering <link>
is optional. Also notice that the user agent has a choice of how to
render or use the relationships defined by <link>. That means that even
if a UA supports HTML 4.01 completely, you have no way of knowing how or
if this information will be displayed.
By contrast, only styling can disable an <a> element.

Whereas you'd have them forced to have two navigation bars, one in
the web page, and one as part of the browser that doesn't even work
because the web page doesn't have any relevant <link> elements.

I sort of see your point, although I think you're confusing author
benefits with user benefits. Consistency is good, but it can be taken to
an extreme. For instance, <link> does not allow for nested menus for
site navigation, nor does it allow the incorporation of a search bar.
Fixed UI schemes are not always best for site navigation.

Considering I have no idea how this <navigation> element will be
implemented, I cannot answer that with any degree of accuracy. Perhaps
we should wait until someone actually describes a new element before we
start attacking it.
