It is a decision with some trade-offs.
I'm surprised you would dimiss it as "stupid" without knowing more about
what problems they were trying to solve, obviously the smallest
compression wasn't their only priority.
One thing Zip has that other archive formats don't seem to have is an
internal filesystem, and some files inside the zip can be more
compressed than others making it a good container format. An index or
manifest can be left uncompressed, whereas other files within the archive
can be more heavily compressed if desired.

There are more detailed explainations available (I read one very long and
detailed report on it when it was first added to OpenOffice) but if you
can find the list of requirements they had it should become clear.
No need to say unpleasant things about OpenDocument.
