This is wery well explained in the Pro Git book, for instance.
And in numerous blog posts etc.

This would present another namespacing issue: how would you name the
branches you're interested in so that they don't clash with your own
personal local branches?  You'd have to invent a scheme which would
encode the remote's name in a branch name.  But remote branches already
do just this.  So you create a remote tracking branch when you intend
to actually *develop* something on that branch with the final intention
to push that work back.

It appears, the distributed nature of a DVCS did not fully sink into
your mindset yet. ;-)
Looks like you mentally treat a Git remote as a thing being used to
access a centralized "reference" server which maintains a master copy
of a repository, of which you happen to also have a local copy.
Then it's quite logically to think that if someone deleted a branch in
the master copy, everyone "downstream" should have the same
remote branch deleted to be in sync with that master copy.
But this is not the only way to organize your work.
You could fetch from someone else's repository and be interested in
their branch "foo", but think what happens when you fetch next time from
that repo and see Git happily deleting your local branch thatremote/foo
simply because someone with push access deleted that branch from the
repo.  This might *not* be what you really want or expect.
