Well, yes, but...
Partly the problem is that the law can be horribly counter-intuitive,
with a mess of confusing and contradictory precedents. But also there
has emerged a doctrine of interpretation of free software licence
(in)compatibility which is not much questioned and has assumed the
status of a quasi-truth even though most of it has never been
established in law. That's why a real lawyer is required: they know
where the boundary between law and tradition is, and thus they are in
a position to provide a truly useful reply.

That sounds like an excellent reason to me.
One other thing: licence questions are often of the form "How can I
get around this licence?" They're not usually expressed in a way that
is so transparent, but that's what they are. The questioner wants to
take advantage of free software but keep their own changes
proprietary, denying their own users the same freedoms they enjoy.
Some people find such questions immoral, even outrageous. Do you
really find that incomprehensible?

An uncharitable reader might interpret this paragarph as "I'll say
anything I please but I will refuse to defend it."
