Sure, it could be an option, but for those of us who have no moral objection to proprietary code, its not a compelling universe to live in.

People who write proprietary software generally take on harder problems before the free software community (from AT&T to Google), and are quite generous with their fortunes once they make them.

I'm not concerned when producers of good things make money, I'm happy when I see that happening, as opposed to non-producers like financial vultures making all the money while being destructive to society.
