If you want total security, go to prison. There you're fed, clothed, given medical care and so on. The only thing lacking... is freedom.
My parents had us very young. We lived in a modest house. We built forts, we hiked, we went camping and they wanted us to be independent. It's how children grew up in the 1940s and 50s: outside all the time, playing in the dirt, riding your bike around.
