Why aren't women and men golfing against each other in tournaments?

I played golf since I was a kid and haven't gotten much better than low double digit handicap because I don't practice and never taken golf lessons. However, I have played with some excellent players and have seen that women and men can play the game as well as each other. Sure the technology has meant balls are able to go further, clubs can impart more energy (speed, rotation etc.) to balls and this made me think that some of the top female pros can match many of the male pros in terms of distance they can hit the ball as far and with as much accuracy as men as well as be as precise in their putting.

Why then aren't there mixed golfing events that are genuinely "OPEN" to all that attract men and women into them? Has the business become so lame it insists on separating into two separate "sports" for egotistical reasons? Or is there something else at play?
