So? Why would that have been such a bad thing?
By your way of thinking we would never have split off from the UK ourselves.
One of the reasons we split from the UK was that a huge natural barrier (the Atlantic) separated us. It resulted in the UK not being able to empathize with the colonies' needs (and would have been the same going forward if we had remained in the sitatuion).
Not so with the continental US of A. There's more power in unity here.
