If you just happen to start with a complete, finished set of data that you
want people to use (as NASA/NGA etc did), then that would be fine.
Similarly, if one person created the entire dataset on their own and wanted
maximum usage of it, then again PD would be a good choice.
The problem is _creating_ and maintaining that data when a large number of
people with diverse interests need to cooperate to make it happen. The
default is for such people not to trust each other with unrestricted access
to their own valuable data, which is where copyleft licenses come in, by
providing a set of "share alike" rules which means that nobody who
contributes data can fail to get the full benefit from it.
