You can take apart every theory. That's the problem with rhetoric: you can prove everything, and you can disprove everything.

Luthien also has great singing powers, powerful enough to beat Morgoth. Does that make her a Vala or Maia? No. She is the daughter of Melian the Maia, so she is a half-Maia. That means Tom Bombadil (who seems to have much lesser powers than Lutien) is at least a decendant from the Ainur, but not necessarily an Ainu (is that the singular?) himself.
