Huh? That's a completely specious claim.

The owner of the rights to the TV show may not be offering the product in your market--yet. The may choose to do so at some point in the future. Whether they do or not, it has no bearing on the fact that you are consuming their product (and infringing on their rights) without paying.

Your argument is essentially saying that it isn't theft of services if a 15-year-old sneaks into an R-rated movie, because the theater won't sell them a ticket.
