On the other hand, the Force (or rather the midichlorians...) could be manipulated to give tremendous powers to a sand-hating little virgin birth from Tatooine. Granted, it was a Sith who did this, not a Jedi, but that isn't something anyone can do. In fact, only one person could actually do it, as far as we know. And making any use of the Force is a power almost exclusively in the hands of the Jedi, a fact drastically downplayed by Luke. The previous movies never made a secret out of the symbiotic and whatsmore special relationship Jedi had with the Force, that these powers were both a boon and a responsibility, especially seeing how rare they were. The Force not being a power that some people possess and a great many others do not are simply not true, just as it would be false to say that the Force is nothing but a power some individuals possess.
Heck, just a few days prior to the scene between Luke and Rey she uses the power of the Force to defeat a trained Force user with a weapon she never held in her life. If that's not a power she possesses then I don't know what is.
