I may be misunderstanding what you’re saying, but it sounds like you’re assuming that women only continue wearing hijab because their families force them to. That’s certainly not the case.
The suggestion was prohibiting the hijab in higher education and subsidizing it, as if the only barrier to conservative women attending an institution where they’re prohibited from dressing traditionally is their parents’ approval. That’s not the case.
But people who think it isn't forced are simply wrong.
