How do you communicate someone's name then? You can't say "the name IS", or "He/she IS called". The cognate to the word all the other Germanic languages use has become archaic and even lacks a present tense form: https://en.wiktionary.org/wiki/hight#English Maybe: "One calls her/him"?
A few more options: He goes by the name Jack. He bears the name Jack. He answers to the name of Jack. Everyone calls him Jack. His parents named him Jack.
For example: I hear "He goes by the name Jack" and I think, "okay, but what is his real name?" Or: "Everyone calls him Jack" implies once again that "Jack" is not his real name. "His parents named him Jack" implies that he now goes by another name, not his given name.
E-Prime is an interesting thought experiment, but it's simply not practical for real world, everyday speaking. I will grant that it can be effective in writing, but it still seems as if it's only trying to prove a point, and aggressively at that.
