I do agree that it's a part of the environment kids will grow up in, so it's important to teach them to careful. Just like how it's important to teach kids to look both ways before crossing the street, to not play in street, and to be increasingly mindful the busier the roads are, but I wouldn't call that "traffic neurosis" or worry that it will cause them to be dangerously isolated and unable to navigate a city.

Kids can be educated about the dangers of data collection, be mindful about the data they are giving companies and aware of how ways that data will be used against them so that they can make smarter choices without cutting themselves off from the world they have to navigate and be a part of.
