You have to realize, if they do offer a standalone service, that they have to hire employees to support it. They have to also hire their own accounting/business employees to support the people who are curious, have issues, need to pay, etc. Not to mention, paying for servers needed, security for the sensitive billing information (which also will require more personnel) etc..
That being said, I still think they should offer it.

On cable, HBO provides the programming stream(s) to the broadcaster and the broadcaster handles distribution to subscribers.
If HBO goes stand-alone over the internet, they will need to lease services from content distribution networks or build a content distribution network of their own.
So doing it themselves is not necessarily as obvious a choice as it may seem.
