comment Must closure be element of topology?
To start with, you claim that $Cl([0,1])=[0,1]$. This can't be true, because $[0,1]$ isn't even a closed set in this topology. Or have you adopted the (non-standard) convention that elements of $\tau$ are the closed sets?

comment weak homotopy equivalence (Whitehead theorem) and the *pseudocircle*
Wikipedia's justification for calling this space 'highly pathological' is that it isn't a $T_1$ space. But the same can be said of any non-discrete finite topological space.
