I am not certain where you are deriving this claim from.

Nor this claim, as well.
I have had many discussions on the topic of IQ, and I have never once seen anybody ever argue that there is no variance in human intelligence. There is a large range of variance in every human attribute. That is not the focus of the debate. Rather, most of the debate seems to be surrounding the construct validity of IQ. Statistical validity != construct validity.

Sure. But in science, we regularly postulate the existence of some construct, and confirm that construct by conducting many empirical tests that return results consistent with the existence of that construct. General intelligence is like that. We can’t see it directly. But we have myriad results that are statistically consistent with its existence.
There's no debate on construct validity of IQ among the experts in the field. The consensus position is that IQ tests measure something real, that the tests enjoy extremely high measurement invariance (which implies construct validity), and that the results have extremely high predictive validity (relative to literally anything else in the entire field of psychology). The current debate is more along the lines, whether the contribution of genes to variance in IQ is closer to 30% or to 80%.
