How do I remove home folder from the desktop?
This has changed under Ubuntu 19.04 "Disco Dingo":
gsettings set org.gnome.shell.extensions.desktop-icons show-home false
Similarly for the Trash icon:
gsettings set org.gnome.shell.extensions.desktop-icons show-trash false
Should you wish the icons back again, repeat the command with false changed to true.
For Ubuntu versions prior to 19.04:
gsettings set org.gnome.nautilus.desktop home-icon-visible false
