bans on unescorted women in public places were based on the notion that women without male escorts were in all likelihood prostitutes.
Or it could be that there had to be some rationale for restricting women's movements, and that seemed as good a one as any ...
It is, indeed, a freakish little story.
Apparently one of the reasons that girls can't attend without a male escort is the fear that without a proper date, the gals will get a little too crazy. Yeah, you know we need dudes to keep us in check.
Back when I was drinking underage, Ontario bars ... oops, the word "bar" was verboten; taverns, with opaque glass windows ... had separate facilities called "ladies and escorts" and "men's" rooms. The establishments generally required a ratio of no more than two men to one woman in the ladies and escorts. We young women were popular for that reason alone; the men did not want to be stuck in the stag room -- although beer there tended to be cheaper -- so they'd offer inducements to accompany them.
Anyhow, the idea obviously was to keep the men under control, and keep them from bothering the "ladies". Large numbers of unescorted men might be problematic.
The surmise about girls getting crazy was from a student at a neighbouring school. The school itself said:

Too bad! I'll be lying awake tonight wondering about this one.
