the proof in the beginning seems inadequate(probably by mistake, the logic in the video proof is circular)-the contradiction is on the part of the convergent subsequence, i.e. if we assume that the set does not possess equi-small tails, it eventually contradicts the convergence of the subsequence of the compact space.
