Basically, the text. If due to X chromosome inactivation and Barr body formation, only one X chromosome is going to be active, why does it matter if one is absent? It may increase her chances of X linked disorders but why is she infertile or suffer any other problems?

It’s a myth that every single gene on the X chromosome is silenced during X-linked inactivation. In reality, many escape inactivation and are still expressed. It’s the lack of these that cause many (if not all) of the problems in Turner’s syndrome.
If you want to read up more on which escape X-inactivation, search “four core genotype” model and go from there
