Hunter x Hunter 2011

Maybe someone like Netero can do this by choice but I doubt anyone else has the ability to give up all their power for one shot.

Who's giving up all of their power for one shot? There's no evidence that's what Gon is doing, apart from the opinion of his enemy who knows far less about nen than Gon. Moreover, from a purely practical point of view, how exciting will the rest of the story be if Gon loses his nen powers here? As far as I know, this isn't the end of HxH. Gon hasn't even met his old man yet, despite the fact he stupidly, or gonnishly, thinks Kite being dead is the end of the world.

The core of this problem appears to be: If someone can just achieve such monstrous power by giving up his own life, why doesn´t everyone do it in face of an overwhelming enemy? It seems logical for me to assume that it´s not as easy as to decide doing that. It makes more sense to assume that it is a result of Gon´s natural talent. Even Netero didn´t really achieve anything by talent, he got stronger by pure repetition and dedication. So, Gon´s transformation is THAT special.

Moreover, from a purely practical point of view, how exciting will the rest of the story be if Gon loses his nen powers here?

In my opinion? Very exciting, since it´d mean he´d have to find new ways to compete with nen-users.

As an aside, finally some positive reputation for me, on the topic of Pitou:

I'd hit it.
