They *are* optional.
The first chapter is about getting the data in and out. That is not
optional for using a database. Transactions, views, foreign keys,
primary keys even, and everything else that some people think is
essential for a "real" database are in fact optional. Remember that
the tutorial is intended for people starting from zero. Let's not
overwhelm them right away.
