This is not entirely true. When you live in my country (Netherlands) and inquire about Freemasonry, you are quickly lead to the Grand Orient. The Grand Orient has the tendency to refer women to the Vita Feminea Textura, rather than one of the three comasonic orders that we have. Of course there is the case of not knowing and perhaps us comasonic organisations should reach out more. But we're with only a few hundred, against some 6000 regulars.
Now this of course supports your theory. Belgium then. 30% Of the Belgian Freemasons belong to Le Droit Humain and there are more mixed and one women-only order. Regular Freemasonry (the Regular Grandlodge Of Belgium) covers only 6,5% of all Belgian Freemasons.
Apparently, it makes a lot where you live. In Belgium there is a much bigger chance that you bump into a mixed lodge than in the USA.
In any case, the above does not talk about regular Masons changing organisations. Some regular countrymates do like to visit mixed lodges (unofficially of course), some do not. All good friends. If less fuss was made about that fact (a man kicked out because attending his wife's initiation into a mixed lodge for example), the world might just be a little better a place.
And for the rest, in most countries people can choose. I decided to attend a lodge 100 kilometers away that I can be member of with my girlfriend rather than one of the 4 regular lodges of my hometown.
