Including Loop is not necessary, but recommended. Also, if you want to use some features you need the loop, for example:

<?php if (have_posts()) : while (have_posts()) : the_post(); ?>
<?php the_content(); ?>
<?php endwhile; endif; ?>

I think you’re also confused by terminology, as the wording in WordPress is a bit, well, confusing.

So all post types, including pages are special types of posts. So “post” can mean the actual usable post type “Post” as well as the general term of all content like “Page” or any other custom post type.

When the Codex says

You use The Loop in your template files to show posts to visitors.

What it actually means is

You use The Loop in your template files to show posts, pages or any other single item of a custom post type to visitors.
