I think that view is criticized because the response to that socialization by cis boys and trans girls is different, which leads to a whole spiral of different social outcomes.
Also, though, there's not just one way to be trans, and there are certainly trans people who view their gender as less innate or absolute. Though the majority of trans people say they have always been whatever gender they ultimately identify as and only their expression changed, others say they really did change genders internally as well - that they were a man and became a woman, for example. They're both legitimate (and probably based on a lot of different cultural influences).
