Voynichese is a numeric cipher?

[ololololo]

There is no way to tell 'read' from 'dear' or 'news' from 'Swen'

Let me add a little bit of speculation here.
Let's say I sent you a letter that I've encrypted by turning the words into anagrams based on a specific characteristic (for example, the weight of the letters). 
The text looks like this:
Dear Joe, please read book and listen silent forest
And I'll encrypt it like this:
DREA EJO EPL EAS DREA KBOO DNA ENLSIT ENLSIT ESRFOT
Knowing other words, you can guess anagrams based on their meaning. However, if I encrypted Listen and silent differently, I would reveal the fact that they are different words. Without knowing anything, you could sit there and measure the statistics, and after 600 years, you would conclude that this text was dictated by a Chinese man to a medieval merchant.
In the case of Voynichese, the same - if we guessed one word, then we mean that we need to either change the order of letters in it, or look at other words, or doubt our conclusion. I do not see the complexity anywhere in the listed.
In fact, anagrams are not a serious problem, unless the encryption algorithm itself is complex, in which case it will be garbage.
