It doesn't have much to do with branching/non-branching. You may use
branches, and still work collaboratively on them. There was an example
above in the same thread:

  http://thread.gmane.org/gmane.comp.version-control.git/192547/focus=192694

There are also cases like "I pushed from my laptop and I'm back to my
desktop", or "the content has been edited from GitHub's web interface".

Actually, I hardly see a case where "pull before push again" (with or
without --rebase or such) is wrong for a beginner.

Very simple explanation exist for what "push" does, but not for "the
global picture of what push and pull do". And really, the case "Git
prevents me from pushing, I don't know what to do" is a problem for
people who don't get the whole remote/branch/upstream/... things.

Actually, I'm starting to wonder if the whole "upstream" thing should
not be deactivated by default, and replaced with a simpler mechanism
like "pull.default", similar to what "push.default" does today. Then,
users could set "pull.default=current", and "git pull" would pull a
branch with the same name remotely. Or users could set
"pull.default=upstream" and get what Git does today.

But that's a much larger change, then ...
