Elephant in the Room Solution Considerations

[Bluetoes101]

The reason is, nobody can claim to have seen the contents of the missing/removed pages, and it can plausibly be considered that their going missing and being removed was an act of forgery to make the manuscript enigmatic and marketable to a highest bidder. I am surprised Voynich scholars have ignored or underestimated that possibility and treated the missing pages as merely incidental.

I think you answer your own question here. Nobody knows what was on them, so your possibility is equally as likely as any other. 
With that being the case, it is sort of is "incidental". If you are in a plane at night and everyone is sleeping with the windows closed, how fast are you travelling? 
Einstein said the answer is that it doesn't matter, because you can't know, you have nothing to measure. 
I think the same logic applies here.

Maybe they contained plain-text instructions to decipher the text and someone cut them out to aid them reading it. 
Maybe they were cut out to make it more sellable.
Maybe they were so damaged someone decided to cut them out. 
Maybe they were deemed to have troublesome content for the person who owned it at the time. 
Maybe it's next weeks lottery numbers  

.. excluding the last one, I don't see how someone can build a compelling case for something we don't have.
What happens is people tend to choose one that best fits their theory.
