I think Esperanto is a fun hobby and I have fun toying with it every few years, even if I'm under no delusion that it's a practical way to, say, do international business. I do think that if it or any universal second language (French, English, Mandarin, whatever) were to suddenly become more widespread, the world would be better off.

My claim was only that the reason that it's not more widespread has nothing to do with subjective flaws in the language itself.
