There are already laws against anti-competitive behavior. If you feel your rights have been violated in this respect, bring action against those who have violated them.
Back here in the real world, I'm having trouble thinking of an industry that is more competitive than home delivery of entertainment video. You have two satellite companies. You have a cable company. A lot of places have more than one "cable" type company. You have Hulu Plus. You have Netflix. You have Amazon Instant Streaming. For movies there is Vudu.
Cable and satellite companies have the challenge of bringing people the content they want using the technology they prefer at a price they're willing to pay. This model developed because this is the model that best delivers that.
