The GPL is a set of restrictions placed on the redistribution of software source code.

No, it is not. Copyright law is a set of restrictions placed on the redistribution of (among other things) software source code. The GPL is a set of limited exemptions from those restrictions, granted by the copyright holder (who is the only one in a position to grant such exemptions). As the GPL says:

5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License.

Note also that the GPL doesn't restrict the use of a program ("The act of running the Program is not restricted [...]"). In fact, it can't -- copyright law doesn't give the copyright holder the authority to restrict the use of the program. Which is why the EULA has to go through the motions of allegedly entering the user into a "contract", in which the user "agrees" to the restrictions on use. That's the key difference between the two: the GPL is based on copyright law, while EULAs are (or purport to be) based on contract law.
