At first look, it seems like simply by having so much less mass of material involved that you have a good head start at competing on LCOE, even if the system needs the kite and tether replaced every 5-10 years.
I think the biggest roadblock would be making sure it can return to the perch with high reliability otherwise you will have a lot of service calls for kites that landed on the ground.
