The suggestions were meant to be placed in the crontab, but that doesn't matter anymore, since the problem has been discovered:

/home/myuser/.Private on /home/myuser type ecryptfs (ecryptfs_check_de

Yes, the home directory is encrypted, so it is not available when the user isn't logged in. One solution is to drop the scripts in a non-encrypted location (/opt or /usr/local or whatever suits your system) outside of the home directory and it'll work.

$ sudo mkdir /opt/myscripts
$ sudo chown myuser:myuser /opt/myscripts
# put scripts in /opt/myscripts
