I pretty much agree. Anthropic reasoning is very strong in some circumstances. If we can directly observe some planet, and see that there's no life on it, then

I pretty much agree. Anthropic reasoning is very strong in some circumstances. If we can directly observe some planet, and see that there's no life on it, then it's pretty easy to answer the question "why are we on this world instead of that world?" The difficult case is the one where direct observation isn't possible. The neutron star example is good: they exist in our universe, but who has strong evidence or argument that there's no exotic life in/on the crust?
