You might be right, but the author of Nuitka disagrees.

I tried the same thing with a dynamic language: translating byte-code
into a series of function calls in a compiled language. So it wasn't
really compiling to proper native code; the native code still had to
deal with the byte-code rather than do the work directly.
It didn't really work: I saved the minor overheads of byte-code
dispatching, but it ended up being slower than byte-code. (Perhaps to do
with worse cache performance and fewer inlining opportunities.)
From looking at the overview in that link, it might be taking a similar
approach. But maybe CPython dispatch overheads are higher, or maybe it
just does a better job!
