So are you saying her choice should be 1. play the desired course layout against a field not desired or 2. play against the desired field on a course layout not desired?
Something to keep in mind is that most players have no sense of what tees provide the best competition for the skill level of their division. Tees that are appropriate for the 1000+ rated men aren't going to be the ones that do the best job of separating scores for the 900-950 rated top women. It's not sexism to provide them with the best opportunity to have the course accurately separate them by score just because they don't understand the rationale behind it. It's the same with divisions like intermediate wanting to play long tees designed for blue or gold level players, it might seem like the most fun but it's not the best competitive challenge.
Building a course strictly for beginners seems like a big waste of money and resources. The beginner will quickly move on to more challenging courses and advanced players will avoid it.
I'm not saying that all new courses should be designed to be as difficult as possible, but I don't think courses should be designed with beginners in mind.
And any veteran player who introduces a friend to disc golf by taking them to a very difficult course is an idiot.
I'm a 950ish rated player and I play beginner courses all the time. When I have 45 minutes, I can go get a putter round in on a short 9 hole course. When I want to take new players out, they have a lot more fun on a well designed shorter course than on a bigger course where they're constantly having to let better players play through. When I lived in the midwest I often played the shorter courses with putters or super class discs when the ground was snowy or icy.
Just because you don't like beginner courses doesn't mean there's not a really big market for them. They're the ones that are accessible to the largest number of players, so they're the ones that it makes sense to install at schools or in neighborhood parks. Getting kids and beginners started on those courses and building our player base is a better way to convince cities to put in higher level courses anyway.
