Nonsense. Anything that is not allowed by the laws of physics is absolutely impossible.

According to you the
thermal CMB is the combined sum of the
non-thermal emission from stars, galaxies & etc. This is not allowed by the laws of physics and therefore it is impossible.

Space is awash in radiation from all sources. If we want to see the CMB we have to remove the non-CMB foreground contamination. So, the foreground from the Galaxy is removed. Point sources are removed. They are all foreground and we want background. If you want to see the CMB you subtract everything from the total that you
know is not CMB. What's left is the sum of what is CMB and everything that you don't know about, along with any uncertainties or errors in the foreground removal process.
You will notice perhaps that when cosmologists use the CMB they generally avoid the region masked out for the Milky Way just to avoid any residual error and uncertainty from the Galactic subtraction.
So the CMB is cleaned of all foreground sources, as best we can do it. It has nothing at all to do with starlight.
