That's an insightful observation and explains perfectly why Netflix does not provide a simple straight list of all titles that you can scroll through. I'll bet that the Netflix engineers have wanted to add such an obvious feature, but someone in marketing yelled, "Don't!"
If you ask the average non-techie user how many titles their Neflix subscription has, they'll be astonished to hear that it's only ~7750 in the US and even less in other countries (eg., ~4478 in Canada)[1]. Even though this information is easy to discover, it seems that most people don't bother to know.
