The physical world equivalent would be if Porsche didn't sell their cars, they only leased and rented them, and the lease terms didn't allow subleasing or renting it out, or even letting someone else drive it. And there were no wholesale or reseller agreements to allow other dealerships or rental companies to lease or rent them out.
If Porsche were to do that, a lot of customers would probably switch to BMW or Audi instead. But with Movies and TV, competing products are less fungible.
