You are forgetting one important thing: you can only relicense the parts
of the software that you own the copyright for! Let me give you an example
of a relicense you cannot do.

Let's say that product XYZ is GPL. You create an improved version, and call
it XYZ++, and release it under the GPL. Now, a client of yours wants to
buy the rights to XYZ++ which will allow them to make their own changes it
and to sell the resulting product without its source. You simply cannot sell
these rights to them! The GPL, the license of the original program XYZ, does
not allow you do to that. The fact that you also release XYZ++ under the GPL
doesn't help you.
