In practice, you'll usually have it, except in cases where the user has
bookmarked your site, typed/pasted the URL directly, had it opened by an
external program, or taken action to block referers from being sent
(this last one is uncommon)

You can refuse to serve the content if it's not present. But this will
annoy users since they can't bookmark it or open it from an external
program.
