Under the stated i.i.d. sampling and standard regularity conditions on the kernel and bandwidth sequence, the argument as summarized contains no visible internal inconsistency, circularity, or unverified step that would prevent the claimed convergence from holding.

This is standard nonparametric statistics and Bayesian predictive inference (Fortini–Petrone CID framework).
