This is a new town and we're all still deciding where the houses and streets should go.
What you're saying seems to be, "If this particular street doesn't happen, does that mean the whole town is just chaos and nonsense and we should all run off elsewhere?"
No, it doesn't. It doesn't even mean anyone else has to tear their house down and flounder in the dirt waiting for consensus.
It just means the people involved renegotiate things and figure something else out.
