Jew and Gentile

Hello Rabbi.
Thank you very much for the website, the books, the articles, the responsa, etc., etc. – I have no words for the many benefits!
Question: Does the Rabbi think that philosophically a Gentile must convert? Is there any such requirement? I don't think so, there is no philosophical consideration that would make it possible to understand that he must convert. Am I right?
If there is no such consideration, the obligation is only on the Jew to fulfill the Creator's command (do and be heard, accept the public, etc.). Are you happy that you are a Jew?
Or in other words: If you were a Gentile, would you convert? I can't think of a real motivation to convert (aside from cultural considerations, enjoyment of sociology, and even benefit from studying the Talmud). Do you think there is something 'real' and philosophical consideration that I'm missing?
I hope I was able to explain myself…
