As somebody else pointed out in the comments, this is a “standard problem” with all systems of “smart contracts”. There’s no equivalent of a Notary Public to assess that your identity is accurate, you’re not being impersonated, you’re not obviously subject to undue duress or coercion, and are not out of your mind. I think that makes this application in particular pretty pointless (if you can get somebody drunk enough to get them into your bed, you can probably cajole them into swiping something on their phone’s screen beforehand).
