In situations where most of the cost to set up a business is upfront, the marginal cost is very low and you can't "move" the immobilized capital after (like power lines, train lines, water main, fiber optic networks), there is a massive advantage to the first entrant (the "incumbent").
In these cases, there are massive barriers for new entrants: any new entrant would have to make an immense investment with zero chance of making it back, as the incumbent could just retaliate by lowering prices and driving the entrant out of business.
This situation means that there is little chance that competition will happen, so it is the best interest of society to mandate the operation of the infrastructure from the service. That's what happens with local-loop unbundling, or when the ownership and operation of the rail infrastructure must be separate from the ownership and operation of train lines and services.
That is not the case with mapping the world: anyone can do it, and having an incumbent doesn't block new entrants. There were already many incumbents when Google entered the mapping business, and there's still plenty of competition.
Therefore, there is no reason to mandate separation.
I have a degree in economics and it's definitely just your opinion, man. But it all ends up being very philosophical and "what's the kind of world you want to live in" type stuff. I'm glad to leave it at agree to to disagree.
Same as me.
