It is problematic, yes.

The much-higher-than-surrounding-communities rates of sexual assaults on college campuses are concentrated in the dorms, so “dormitories do it” is maybe not a very good argument that it is a good idea for a broader population.

1:1 bathrooms to residential units are going to make you need to extend the plumbing considerably, at which point what is the point of not doing it to the individual units? Also, bathrooms aren’t the only reason habitable units need plumbing, kitchens need it, too.
I know that shared bathrooms and kitchens would be less desirable. But if that meant paying half the rent? It's not for everyone, sure, but I'm also sure it would be suitable for a lot of people.
I would have preferred a single in college when I lived in a dorm, but the bathroom and kitchen down the hall wasn't a problem for me.
So could government support for the cost of conversions which just don’t leave this issue in place; women aren’t the only population for which a remote bathroom and kitchen are problematic.
Unfortunately, that kind of housing has been zoned out of existence in most of the US.
You'll need to install separate electric service to each unit unless you want to share an electric bill with your neighbors.
You'll need separate HVAC unless you want to have one common thermostat and keep your home at the same temperature as everyone else's.
You'll need walls, and they really ought to be built to block some sound. You need walls that separate units, and each unit also needs internal walls since you probably want things like bedroom closets which office buildings don't usually have.
You're going to want a kitchen with cabinetry, appliances, and plumbing for sink and dishwasher.
Since you're building all that, you can just add plumbing in while you're doing it, either inside those walls you're building or along the ceiling.
What's effectively being suggested in these threads is a hostel and they already do exist in a number of cities, even in America (although they're more popular elsewhere).
I haven't seen a hostel create a "floor" in prices the way you describe. A really terrible motel is often cheaper than a nice shared hostel room. Even if it wasn't it would be a leap to say that new housing caused existing housing to go up in price.

This is the counter argument I'm considering. It really depends on the market incentives for landlords, and how that pans out. Whether an increase in shared-facility rentals result in a decrease of prices for non-shared rentals, or whether it results in equivalent numbers of non-shared rentals getting pulled out of the rental market entirely, and the remaining ones priced upward.
Is it so unthinkable to have bathrooms "down the hall"? After all, dormitories do that. The bathrooms don't even have to be shared, they're just down the hall where the plumbing is.
