In fact I wonder why there is not a version without the front facing camera

The same reason why there's no TV without a remote, no Laptop without a keyboard and no tablet without a touchscreen.
It's its main input device. To actually be useful, and not just a very small, very bad GoPro, you have to be able to point and ask at a party: "OK, Glass, that watch there, how much does it cost and where can I buy it?" or, with the kids in the zoo: "What are these animals called?" or "Where am I and how do I get home?"
Microphone only would be pretty lame, I think.
