The looping has nothing to do with -x, and I see nothing that
indicates -x has failed in its desired effect.

The loop is generating a source filename
/home/richard/.local/share/Trash/expunged/73080846/grub2 problem-2018-02-13/grub2 problem-2....018-02-13/grub2 problem-2018-02-13
which is likely within length limits, and resides on the correct
filesytem. However, the destination filename is lengthened by
prefixing it with /media/richard/MISC backups/dev_sda14 which
takes it over the pathname's limit, which is what the error
message states.

Cheers,
