What does it mean to "export", and why would you want to do that to a
TODO list? Why would it be important to put properties on parts
of a TODO list?

​Org mode is part markup language and some of this markup is used when exporting org mode files into different formats like HTML and PDF for all the reasons those formats are used by anyone, just like you would with a Texinfo file.
