Yes, we are a resource, like the European rulers and explorers saw other continents at the beginning of the era of colonisation.
Nobody important lives in the Women's Country, so it is for the taking. And it's fine to cosplay its natives and to redefine its laws (such as what counts for being a citizen, not being born in the country), to ban its language (we are now wombcarriers and menstruators etc.)
I can have empathy for Bergdorf's suffering, but Bergdorf appears to have very little empathy for the indigenous inhabitants of the Women's Country. Even the way Bergdorf creates herself as woman reflects an outsider's view of what a real woman is (desirable to men, seductively dressed, fully made up, irrespective of the time of the day and context).
Your point about women being a resource is so important in this context: We are validation resource, we are an applauding resource (in sports), we are a resource for various imaginary interpretations of womanhood, as seen from the outside, and, last but not least, we are mental support staff resource for the rest of the world.
If we fall short of those, then we deserve great wrath. I think this follows if you equate 'woman' with 'feminine' which seems to mean passive, submissive, emotional and nurturing. The very definition of a self-sacrificing support cast.
