Interesting post....... My initial reaction: insecurity. I say this because you never hear ivy league students bragging of how they will take over the profession and that everyone else must accept it and conform.
I applied ED to Duke. I didnít think I could get into a better school (Iím an URM). I got into Duke but then got accepted by Harvard! Is there any way to get out of the Duke commitment? What if I wait a year and ask Harvard to defer my acceptance?
The only way out of it is to withdraw all law school applications, including throwing that harvard acceptance under the bridge. You can tell Duke that you have decided not to go to law school. In the following year, you can reapply and say that you have decided to attend law school after all. However selling yourself again may be difficult - they will wonder why you turned them down the first time.
I believe, if I'm not mistaken, that ED only means you have to commit to that law school only if you decide to attend law school. You have the fundamental right to not go to law school at all next year.
That said, I'm not sure how you could have underestimated the strength of your application to this degree. Applying to Duke ED is for people who have zero chance of getting into HLS. Personally, I think you are too misinformed to deserve that Harvard acceptance, IMO.
