Looks to be about.... 10? times the cost of a normal elevator if I had to guess. I bet the maintenance costs are fun as well. As such, doubt you will see these except in niche buildings (things like the porsche tower, etc..)

The tallest skyscrapers have issues with elevators because the cables can only be so long before they snap under their own weight, so you need elevator changing floors, which take up space and lower throughput. Either you find flexible materials with a higher tensile-strength to weight ratio than steel or you forego cables entirely.

Classic elevators also need a lot of floor space to achieve good throughput. This system is basically like a paternoster on steroids; it can rise much higher, move much faster, use arbitrary circuits and has none of the safety issues. Even if this system only saves, say, 40 % floor space, it'd still be a win for many projects.
