If a girl wants to play a sport for which there is a boys team but not girls team, she must be allowed to try out and participate on the same basis as the boys

Sure. And occasionally you get a girl to qualify. Sarah Fuller as the place kicker for Vanderbilt Commodores, for instance.

But the disparity in builds - particularly in a high contact sport like football - makes women qualifying virtually impossible.

So for example, if you cut funding to a boys team and parents more than make up the shortfall in donations and fundraising, it’s entirely possible based on that you might have to cut it further.

This was in response to early efforts to effectively privatize student athletics and freeze women's sports out.

I'm sure it's a matter of time before our current patriarchy fetish SCOTUS to reverse this out. But for the time being, you can't just find a few mega-donors to create a "Private Men's Club" on a public campus. What is ultimately being measured is access, which does get nebulous, but is necessarily the case when so many misogynists are intent on digging out loopholes to render Title XI toothless.
