Naming a star and owning a star are 2 different things, especially if you don't care if your star has hundreds of other names by other people. This is because star registries are not offical astronomical registries and each registry is independently owned and operated. Basically the registries are a gimmick and that's why it's so cheap. Owning a star...well, as far as I know I don't believe that is possible given the International Space Treaty.
