As Hollaar (http://digital-law-online.info/lpdi1.0/treatise2.html) 
noted, you don't have to agree with that statement (but see "more 
accurate statement" below).

Just because the GPL states something doesn't make it so.  In particular,
there are a couple of mistatements of the law there.

The first is that "nothing else grants you permission to modify ...
the Program."

17 USC 117(a) DOES grant that permission in a special, but important
instance:
       Notwithstanding the provisions of section 106, it is not an
    infringement for the owner of a copy of a computer program to
    make or authorize the making of another copy or adaptation of
    that computer program provided:
    (1) that such a new copy or adaptation is created as an essential
    step in the utilization of the computer program in conjunction
    with a machine and that it is used in no other manner ...

There is nothing in the GPL that says that a person is not the "owner
of a copy" of the program.  So, as long as the adaptation (modification)
is "an essential step in the utilization of the computer program in
conjunction with a machine" it is permitted without the GPL.

The second is that "nothing else grants you permission to ...
distribute the program."

17 USC 109(a) states that:
       Notwithstanding the provisions of section 106(3), the owner
    of a particular copy or phonorecord lawfully made under this
    title, or any person authorized by such owner, is entitled,
    without the authority of the copyright owner, to sell or otherwise
    dispose of the possession of that copy or phonorecord.

However, you can't dispose of the possession of a computer program by
rental or lending.  See 17 USC 109(b).

So, a more accurate statement would be:
    However, nothing else grants you permission to modify AND
    distribute the Program or its derivative works.  These actions are
    prohibited by law if you do not accept this License.
