There may be alternative services which do not look to place any restrictions on where content can be viewed, which will place pressure on HBO, however, as long as a particular provider produces unique desirable content that they are comfortable monetising in specific ways, whatever restrictions that provider wants to place on viewing will remain. It may not make much sense in the example, but the idea still applies. When you buy content from that provider, you agree to their terms and their methods of distribution. As such, there will never be a right to view content wherever you wish, unless the particular provider distributes in such a manner.
