If we can do all text formating in CSS then why do we even learn them in HTML?
Some apps like pocket allow you to save web pages for later offline reading, the css is not used at all, the app applies its own styling to the html in the document, there are many other cases like this so structured, semantic HTML is super important.

It makes it easier to see the hierarchy of your page content when looking at your html code. Also heading tags (H1, H2) are important for search engines working out what your headings are.
