The hub you cite is not inferior.

1.) The operation of the hub is entirely different.
2.) The hub is not required to withstand the transient torque of direct drive.
3.) The cog is driven rather than the axle.
4.) The hub freewheels rather than operate in fixed mode.
5.) The tolerances required are much less restrictive.
6.) The strength requirements are much less demanding.
7.) The market for that hub is at least two orders of magnitude larger.

Using the SEARCH feature in this forum would help you explore this independently.
