I absolutely disagree. Adulthood is freedom. It's when you decide what you choose to do. Sometimes things feel like you have to do them but that's just remnants of the conditioning you were moulded by as a child. When you are pressed to the wall you are eventually forced to understand that you don't really have to do them, you just choose to, because however hard they may be it's easier for you than the available alternative. You don't have that level of agency as a child when you are constantly exposed to indoctrination from everybody more powerful than you (which at this stage is pretty much everybody).
Freedom? That has not been my experience of adulthood. To me adulthood is about making responsible choices based on their consequences for you and the people around you ... which means that the majority of my time is spent doing things that other people need rather than because I want to do them
