Structure is legit. It's similar to discipline, and that's also legit.
I understand what you're saying and am the same actually, always challenging the structure, what's normal and (possibly) in need of a change; that way things improve, or are, at least, confirmed to be legit just the way they are.
As for DST, I don't like the manufactured concept and how it shows humans to be unable or unwilling to accept and work with the world around them; some may say that's somewhat closed minded of me, and that's ok, their choice to think how they think.
