I didn't miss anything.
"ls -l ${daemon_user}/.ssh/config"
Which translate to "ls remoteuser/.ssh/config".
That file does not exist (it's not an absolute path so if you run it from
anywhere other than /home, then it won't be found).
When you append /home you are doing:
"ls -l /home/${daemon_user}/.ssh/config" which translate to an absolute path:
/home/remoteuser/.ssh/config.
