comment Irrationality of $\pi$ another proof
If $\alpha$ is irrational, you can find such a sequence (the sequence of convergent's numerators and denominators, for example). So the proof you are looking for does exist :p

comment “Poissonization” and intuition
If you want to prove that $N_1$ and $N_2$ are dependent, you have to find two subsets $A$ and $B$ of $\mathbb{N}$ such that $\mathbb{P}(N_1 \in A \mbox{ and } N_2 \in B) \not = \mathbb{P}(N_1 \in A)\mathbb{P}(N_2 \in B)$. In your post, there is no such $A$ and $B$, and this is where you are wrong.

comment Simply Connected domains.
Unless it is $\mathbb{C}$ itself ! If you want to prove this result with complex analysis, you should at least choose your $f$ to be biholomorphic.

comment Does “locally connected and path-connected” imply locally path-connected?
Next time, you could use austinmohr.com/home/?page_id=146 It's a searchable database of the counterexamples that you can find in the book. Unafortunately, this time, your counterexample was not known...
