Hell yeah. I feel like if the world ended there would be a group of trans woman with a wind powered experimental estrogen generator inside of a week.

I mean, it's just a fancy hydrocarbon, and in some form or another can be extracted from female mammal urine.

I imagine there's a way to genetically alter yeasts to make estrobeer while they're at it, with the side benefit that the alcohol would serve as a natural testosterone reducer for a double d whammy.
