Let's Encrypt want to do EV too - they've also asked CertSimple for help previously to do it. it's significantly more work than automating DV again (which has already been done) are CertSimple are far ahead of the entire SSL industry when it comes to speedy EV validation.

Encrypting something with a public key, without knowing who that public key belongs to, largely defeats the purpose of encryption.
