Moving out at a young age is only a norm in just a handful of countries, mainly the English speaking ones. Reason being that they were more developed than the rest of the world, making it possible for them to move out when they turn 18. Poverty is a big reason why families are closer and live together for a much longer period. But many of these developed nations seem to be regressing these days, with more money flowing upwards than downwards.

I agree though. The best time to move out is after you’ve worked and saved up enough for a down payment for your own place. Those few years are perhaps the best opportunity to save up that most of us may never get again.
