Web1 Answer. Yes, it works. An alternative approach would be to try to do it in two steps, and take a conjunction. First would be "someone has internet" exists X. I (x) and second would be "if two people have internet then they are the same person" forall x,y. I (x) and I (y) -> x = y. This way is 'simpler' in that there is less quantifier depth.
