There is no such right in the general case. §103 of Title 17 reads, in

You cannot claim copyright on a work that you had no right to create.

Of course. But where does that authorization come from? The GPL! Without
the GPL, the user would have no right whatsoever to create or license
any derivative work under any license. The GPL has increased the number
of possible licenses for the derivative work from 0 to 1.

It can say that because modification and distribution are exclusive
rights of the author, _and_ because there is no other way to do those
legally except by using the GPL.
The latter half isn't always true! Suppose the author of a GPL program
offers an alternative, commercial licensing scheme, and I buy it. Suppose
the commercial license grants me the rights to modify and distribute the
program, and I do so. Do I indicate my acceptance in Clause 5 of the GPL
by modifying and distributing the Program? No! Clause 5, as with the
rest of GPL, only works because the exclusive rights offered are not
available from anywhere else.
