I have a really important question. Really.
So when they scan in/digitise books: why do they keep these blank pages?
I understand that it would feel strange deliberately leaving them out, but why is that?
What is there function and where did they come from?
Is there actually a genuine reason for preserving them (the simultaneous preservation of book design as well as the text perhaps?)?

I have just always wondered is all.

Probably just easier that way. Whether it's automated or a person flipping the pages, it's going to be easier mechanically to just do every page. Then after the fact there's no surefire bulk/automatic way to cull them without possibly losing other important information, and they're such a small portion they're almost insignificant file-wise, so they're left.

Because it's a scan of the book itself, a physical object. It's preserving much more than just the text.
