This drive train simply can not handle high torque as the chainrings will bend under load. They admit it themselves. Increasing their thickness will cause a whole lot of compatibility problems and also turn the whole thing into a monster.
This expensive ceramic bearings are exposed and will experience significant wear. Properly insulating them would wipe out whatever miniscule gain in efficiency they claim as the insulation increases losses.
Finally reducing chain friction (which is already very low on a tuned drivetrain) to some fraction (that has yet to be proven for real conditions) is tantamount to snake oil in my opinion.
These are just few. I could go on but it is not worthy the typing and mental efforts.
