You said that FHE is an oxymoron, seemingly on the basis that in proper encryption the ciphertext is indistinguishable from noise, and you think this can’t be true of FHE. I am arguing to the contrary.

In the secret sharing multi-party computation schemes, the individual shares of the secret are random and have no information about the plaintext.

I see no reason that FHE can’t have ciphertexts indistinguishable from noise.
