Manipulators can manipulate their own nen, it doesn't have to be an outside entity; Razor manipulates his own Nen in the form of his Devils, Goreinu manipulates his own Nen in the form of his Gorillas, etc. Granted, while both of the previous examples are emitters, they are still incorporating Manipulation into their hatsus, and are both manipulating their own Nen.

And using such logic, would you say that Neon/Chrollo is also manipulating time in order to give fortunes to people? Would you say that Meleoron is manipulating reality in order to activate God's Alibi? Moreover, the nature of Nen shown in the show and the different Nen types means that it isn't impossible to copy someone else's hatsu, unless their hatsu falls under specialisation. As such, unless you're saying that a powerful manipulator could recreate any of the examples I have given to at least some degree, they must fall under specialisation.
