The fact that ECC doesn't provide an encryption function is actually a feature, in my opinion:

It's impossible to accidentally encrypt a message with the asymmetric cryptographic primitive in the ECC case, but not in the RSA case. This makes ECC misuse-resistant in a way that RSA isn't.

(Although, strictly speaking, you can "encrypt directly" with elliptic curve schemes if you use ElGamal--which might even be desirable in weird systems. Fortunately, most high-level cryptography libraries that offer ECC don't expose the APIs to facilitate this.)
