The reason for PDF „export“ is it’s origin. PDF in its early days had to be “printed” or “distilled” in a separate application because the process behind the format is the same as sending your file to be printed on a printer. This step changes the (editable) human readable file into (locked) printer readable code in the form of “post script”. PDF is in short nothing but a container that wraps around a bunch of post script code and makes it human readable again.
