So it turns out that I didn't ask my question clearly and was so confused why you all thought I was a brainlet. I meant to ask was why the infinite union was not possibly equal to B (proper subset?). The solutions manual had it differently and this one I understand. Thanks for making me feel bad about myself because Rudin's assblasting isn't already doing a great job of it. I'll be clearer next time, /mg/ has actually helped me out in the past.
