Can all-access be paid for by cash/gift cards? If you were a 12 year old and wanting to watch trek, but your parents were unwilling to subscribe to CBS all access even if you were to pony up the money, that would be an issue. Amazon/itunes gift cards are available, but not for CBS.
Your average 12 year old will figure out how to watch it, even if Mom and Dad won't pony up for it. Though I'm not sure how many 12 year old's are waiting for a new Star Trek series. Enterprise went off the air before they were born.
