Managing a website includes all kinds of other procedures apart from registering a domain and linking it to a couple of websites that are uploaded on a server. Each one of them is critical and influences the user experience - both for you as the website owner and for your visitors. For instance, a script-driven site uses a database, files are uploaded using FTP, and communication with clients is done using e mail, although some services demand certain domain records to be created. Each one of these things is essential and in case any of them is hard to handle or is simply lacking from the list of services your account provides, the functionality of your website can be limited, plus the overall control over the website could be very annoying if you are unable to execute some task.
