Running an Internet site involves all kinds of other operations aside from registering a domain name and linking it to a couple of websites which are uploaded on a hosting server. Each of them is critical and impacts the user experience - both for you as the site owner and for your site visitors. For example, a script-driven website uses a database, files are uploaded using FTP, and communication with customers is done via e mail, although some services require particular domain records to be set up. Each one of these things is crucial and when any of them is hard to manage or is simply absent from the set of services which your account provides, the functionality of your Internet site may be limited, not to mention that the overall control over the site can be really irritating if you are not able to do some task.
