The EU copyright directive formalised what was already the
acknowledged position, at least in common law jurisdictions: namely
that to use software generally involves making a copy of it (when the
software is copied from a storage medium into RAM, for example), and
hence requires the consent of the copyright owner.

I'm not sure I agree with that as a blanket statement. The problem is
defining "lawful acquirer", a term originating from a (largely)
pre-downloading era. It should be noted that the UK implementation of
these provisions refers to "lawful *user*", which is defined as
someone who "has a right to use the program", whether under a licence
or otherwise. Now it's possible the UK has misimplemented the
directive here, but it seems more likely that the term "lawful
acquirer" was always intended to mean "someone who acquires the
software in such a way that they have the right to use it".
And the recitals to the directive emphasise that this is a "limited
exception" to "allow the reproduction technically necessary for the
use of that program by the lawful acquirer". If the intention was to
create something akin to a doctrine of exhaustion for software - so
that only the original licensee needs to have a licence at all - then
this would have been stated more categorically.
It also seems to take us perilously close to the ever-popular "Google
Images fallacy" - i.e. "If it's on Google Images, you have the right
to use it".

For the reasons outlined above, I don't think it is as clear as that.
It probably doesn't make a great deal of practical difference anyway,
given that the GPL allows unrestricted use and modification in the
absence of distribution/conveying. If you want to distribute/convey
the software then you can only do so under the GPL.

Agreed. As I understand it, "exhaustion" only applies to resale (etc.)
of copyright works that have previously been lawfully placed on the
market within the EEA - i.e. I can sell books and CDs that I've
previously bought. It does not extend to the right to restrict copying
of the work, and that is why it is of little help as regards software.
