I am aware of that approach. Actually, I have defended such a view in
a Dutch law journal in an article regarding the validity of the GPL to
Dutch law. The reception so far among legal scholars and professional
lawyers has been along the lines of 'interesting idea, but runs into
troubles because of the limitation of liability and warranty'. I think
as far as Dutch legal minds have given a thought to the subject, the
consensus is that the GPL is a EULA which is more akin to a
shrink-wrap license than to a grant. It is more or less impossible to
set the liability question aside. The conditional grant doesn't mesh
well with the 'normal' way of legal thinking here.

Which essentially is the same thing as the principle of protection of
legal interests I mentioned.
