It's not so outrageous. The GPL starts with a copyright and verbatim copying
permission for the license. Most other licenses don't appear to have
addressed this issue.

All software authors have the right to create a new license for their work.
That doesn't mean they should create a new license. Exactly for the
consistency you speak of, it is better to have a limited number of
well-known standards. Think of it like internet protocols. Having a few
competing protocols is good, while having too many (for example each mail
application inventing its own protocol) is not.
We already have a number of licenses existing today. If authors continue to
make new licenses (even by changing a single word of another license) instead
of adopting one that exists, how many licenses do you think will exist fifty
years from now? Nick's confusion is nothing compared to what future
generations will face.
The other advantage to a well known and limited set of licenses is
automation. It would be nice to create a database that can answer
compatibility questions and let you query by general concepts like "free
software". If some author derives from a free license by changing just one
word, no computer program (or even average person) can tell you if it's still
a free license anymore. The same goes for whether compatibility with
other licenses has changed. You have to call a lawyer.
