Do you have a source where Girard claims that mimetic desire is the only way we develop desires? The closest quote I could find from him is that "All desire is a desire for being". But I'm genuinely curious if you know of a quote where he claims that mimetic desire is the only kind of desire that exists.

How about the one I already cited, where he's being interviewed and says:

I think desire usually is born out of the contemplation of someone else who is desiring and who designates to you the object he is desiring as desirable.

"usually" is not the same as "always", admittedly. But it's fair to say it means "more than 50% of the time, maybe much more."

I would probably agree with Girard that "usually" is accurate if you consider the aggregate of human behavior
