Well I think that at least in some cases there are other options, though I'm not sure how realistic they are in modern society. Where I grew up it would be considered highly inappropriate for a man to coach girls sports. It was taken as a matter of course that girls should be coached and supervised by women.
This attitude comes with other side effects that might not be desirable, and it doesn't do much to prevent the rape of young boys. Still, there is a partial mitigation here if you want your daughter to be able to compete without having the gatekeeper be a man.
As an aside, I am vaguely aware that cheerleading is considered a legitimate competitive sport, but my only exposure to it is from NBA and NFL, where it seems to me a rather ridiculously sexualized objectification of women. I love watching football but I wish they got rid of the cheerleaders. And if I had a daughter, I'd rather she take up a sport like football or basketball or soccer or motorcycle racing than join a cheerleading squad. I acknowledge that my biases here might be way off base. Please show me where I'm wrong, I'd like to understand what I'm missing. Why are people in the west in with this?
Up to college, cheerleading is a serious sport (see, e.g., the Netflix docudrama or even the old movie Bring it On which is surprisingly accurate).
It is one of the most physically demanding sports, and in terms of injuries it is the most hazardous sport for competitive athletes. It's basically gymnastics, but faster, with a dozen or more other people within the same limited space, and people are getting tossed around or jumping off other people, or balancing on top of one or more other people who may themselves be balanced on top of other people.
The only way to achieve this is to not have ambitions and not try to be competitive. And even then you are not sure, because she still want some job.
I dont think it is good overall solution.
