Because a dorm is not an apartment building, it's a place with communal spaces like bathrooms and showers so you have to share some intimacy with people living at the same floor as you. And many people are not comfortable doing so with people from the opposite sex.

Being not comfortable with it is not the same as banning it school-wide. It's perfectly reasonable to have some single-sex spaces that people can choose if they're uncomfortable. But requiring that all dorms be single-sex makes it sound like there is some other religious/conservative nonsense at play.

Regardless, this isn't Victorian England. Men and women mix and live in shared spaces. There are plenty of adult living spaces in the world where people have their own apartment/room, but share bathroom space. That's also common in lower end hotels/hostels for travelers. Requiring that college students live in gender-separated living situations is a bad way to prepare them for the real world.

Most of those dorms are not single bed. Yes, there are hostels. But you're not going to expect that it's going to be common to say "yes, I have no issue getting undressed/naked/dressed in front of my opposite sex dorm mate on a daily basis, or having to go to a bathroom and to do so within a stall" (because the dorm mate (plus whatever other dorm mates of either sex are around).

I get it - and at my stepdaughter's school there are co-ed dorms of different styles. But what they don't offer, and in this case is what the students hoped to achieve was "give us our own dorm with one bed", effectively.

The issue then also comes down to "well, college relationships aren't always the most durable things" - what happens when they break up? Who has to move out? It's not one person's space. Now the college is also on the hook for ensuring that there's sufficient vacancy (wasted) to handle these situations in other dorms.
