But we don't have to imagine a random alphabet which Voynich might have been written in. We can look at the actual language in the manuscript. It often shows three or four Latin-like glyphs repeated. Unless you have access to some special way these symbols are differentiated or otherwise convey information, a way that all other would-be interpreters have missed, you really don't have an argument.

And as far as European thinking goes - there's no evidence I know of a non-European origin to the manuscript.

Edit: and the languages you cite have a larger, not smaller information content than European languages, see;
