You use the star nut to set the preload, but the stem clamp around the steerer is what keeps it all together.

It looks pretty well thought out, and the swivel is nice if you're tight for storage space. Someone mentioned cargo bikes, I think there are some folding bikes that use a similar setup.

Personally, I just don't see the need for an on-the-fly bar height adjustment. Other than fleet/rental bikes and folders.

If you feel like you need a little bit of height adjustment, an adjustable-angle stem might be a less-involved way to get it.
Either way, I would go easy on the curb-hopping and practice learning how to land 'light' on the front.
