Yes, i see what you mean
However, it is question begging because it arbitrarily declares that naturalists must believe only in the illusion of the "real thing", without evidence that there is such a thing as the "real thing". It makes no sense to talk of illusions of X without first independently deducing the existence of X. So, the best it can be said, is that naturalists believe only in the illusion of what theists believe, for instance in a metaphysical intelligence, which could very well be just a figment of the pious imagination.
Ergo, that line of arguments leads to naturalists holding an incoherent position, under the unproven assumption that naturalism is wrong (the "real thing" exists). And that is circular.
Which is not surprising, considering that all so-called logical arguments for the existence of God suffer from the same exact logical disease.
