comment Why can we find forces like this using energy methods?
Gerard, I am describing the asymptotic behavior of the integral to first order in $\mathrm{d} \theta \equiv \theta_1 - \theta_0$

I suppose what you want to know is something along the lines of, "What motivated people to come up with that definition of work in the first place?" I don't know, but that's a different question than the one I was answering, which was an accusation that the logic is circular.

I fixed a mistake in the derivation. I'm not sure what you're asking for with "how do we know the work formula"? I am taking that as the definition of work.
