You sound like you know what you’re talking about. Is your final point that there are no paradoxes in the current standard model? Or that is it rather that there may be but they are not quite what the author says.
Full disclosure: I was once a physicist. I am not one anymore. I've tried to keep my hand in as an interested layperson, but my specialty was never Cosmology or Particle Physics. When I was a scientist I was a Condensed Matter Theorist. That was long ago.
That said, I'm not as sanguine as some people that we are "very close" to a Theory of Everything. There still seems like a very great deal of work to do. Including some VERY BIG ideas that we don't yet have.
