"Having parents", "having supportive parents", "having parents with resources (that can come in multiple forms like time, knowledge, connections, and money) that they are willing and able to use on you", and "having a place that you can live in potentially rent-free whether or you're going to college, working, or need to return to if you lose your job" are things that some don't consider advantages, even though they should. Those things are springboards and safety nets that not everyone has access to.
