Really awesome read. I agree that a boxless world is what we should be aiming for. But right now, isn't that unrealistic? Isn't it the ability to define cisgender a way for trans and other non-binary conforming folks to also organize and protest, which is very necessary right now in our social climate. Similarly, when people argue that there is no race, but the human race? The reality is that oppression does exist because one group has more privileges and can often determine the rights of the other group. So while we should strive for boxlessness, maybe the ability to define these labels right now is necessary for anti-oppression movements.
