He's saying that women tend not to vote libertarian, not that they shouldn't be allowed to vote.

Why misrepresent this (as so many have in this page) when we can all follow the link and read for ourselves?

More context: " The 1920s were the last decade in American history during which one could be genuinely optimistic about politics. Since 1920, the vast increase in welfare beneficiaries and the extension of the franchise to women — two constituencies that are notoriously tough for libertarians — have rendered the notion of “capitalist democracy” into an oxymoron.

In the face of these realities, one would despair if one limited one’s horizon to the world of politics. I do not despair because I no longer believe that politics encompasses all possible futures of our world. In our time, the great task for libertarians is to find an escape from politics in all its forms — from the totalitarian and fundamentalist catastrophes to the unthinking demos that guides so-called “social democracy.”

So, he literally says he doesn't despair this.
