I guess what I don't understand is why I have to specify the location of the public key locally and not on the server. I tried to specify the location on the server but always got the error "cannot open file"

I'm glad you made it work!

Figuring out the public key is not the job of the server, it is the job of the
client to pass that on to the server.

With curl we have to point that out like this due to deficiancies in the
underlying libssh2 library. It is possible to deduct the public one from the
private one, and libssh2 has gotten that ability recently but we haven't yet
made libcurl able to use that functionality - and perhaps you're not even
using such a new libssh2 that would be able to.

Patches are of course always welcome!
