That is quite literally arbitrage. People with families aren't often willing to accept the living conditions they'd need to in order to live in NYC while paying market prices. So they arb and get suburban living conditions with urban employment. The cost of their decision to do that is mostly borne by the respective communities (home community loses economic productivity and then city community bears increased infrastructure consumption). We would know there's zero arbitrage when zero people did this. Which again, I don't think is the goal to shoot for. But simply asserting you have some god-given right to make this arb indefinitely at zero cost is a losing argument.
