I don't think the author is saying "why front end application development hard?" so much as "why is setting up a website hard?". On one end of the spectrum, simply putting content on a website isn't so hard, right? On the other end, making a web application is understandably difficult. Features like users, payment forms, and email confirmation (so e.g. the website can be used for a course) sounds like they ought to be as simple as the former, but are closer to the latter. Is the value proposition from the website building websites like Wix that they take care of the hard stuff?
