"No, one shouldn’t" suggests that you don't use public key when encrypting data. "Verifying a signature […] is […] “decrypting with the public key” is the part I meant when writing that the original statement is "cryptographically inaccurate" - it's algorithmically feasible. But also mind that this specific kind of encryption has a specific name - "signing". You can't state that: "no, one shouldn't use public key for encrypting data".
