His point is that that kind of person is not the only kind of person,
so to base an argument on what they want is as weak as basing an
argument on what he wants.

That sounds pretty sensible to me too – much like darcs asks what your
email address is the first time you work on a repository, cabal should
probably ask the first time you run it "do you prefer global or user

I think this is a case of not seeing the costs to the other users
because you're firmly entrenched in your camp. I would have said
originally that the costs are asymmetric too – but that it's a much
greater cost for the people who expect all installers to do global
installs. So I think that the question asked there is a very valid one.
However, I do like the solution of not giving any default.
