Cmon. Corporations may be a kind of legal fiction, but there is
nevertheless a natural law aspect to them, not just economic expedience. A
group of people freely choosing to act in concert should have some of the
rights of those group members as individuals, and have the ability to
restrict the sphere of activity (both overt actions and liability) to the
chartered purpose.

You might as well say nations only exist for economic benefits. It is more
than that.
