Without the presence of natal women it's just a room.
Precisely. Which when you reach this level, confirms that this is at heart not about a safe space, or a non dysphoric triggering space, this is about a requirement to be with natal women. Whether or not they wish to be consent is irrelevant, and that makes it inevitably a case of wishing to use those women. But not use any part of them such as their minds... feelings... lived experience... thoughts... all of those bits are wholly surplus to requirement. So what bit of natal women is required?
And yes, it's a very ugly thought but when it becomes clear that compulsion to provide physical presence has become a relevant issue, it can't be skated over for the sake of niceness any more. Natal females know about this business of having certain aspects of them seen as property and their consent being irrelevant to the process, it's at the heart of why natal females have sex based rights.
