Why does the Librem 5 phone cost that much?

>>fghtr+(OP)
This great Dev Kit design is available for everybody: https://kicad-pcb.org/made-with-kicad/librem_5_dev_kit/ Amazing piece of open source hardware. While I am not interested in cellphones, I might use for robotics project.

Would that allow a hobbyist to make their own version of the phone? If so, I could see that being a fun project.
