If he had not opted in to that, only the NSA and intelligence-industrial complex would have had access to his Google location history, while with that option, regular police had enough political clout to demand it. They might lose that ability (although even that is not entirely clear), but the under-the-table mass surveillance of everybody will continue just like before.
