comment Does there exist $k\ge2$ s.t. $X \subseteq \mathbf N^+$ has positive upper Banach density if the counting function of $X$ is $\gg n/\log^{[k]}(n)$?
Perhaps I am not understanding the question, but isn't the set $$A=\{n\lfloor\log^{[k]}(n)\rfloor : \ n\in\mathbb{N}\}$$ a counterexample for any $k$?

@TerryTao: That's a great example. I shouldn't have only read the part of that blog post about applying the heuristic to the ABC conjecture, as you gave this example there at the start!
