I believe that's incorrect, unless by "lease" you mean "uses without paying".
Seriously though, the length of a line for a service is part of the quality of that service. For what kind of service transaction would you say that the wait is not related to the quality of service? Since the lines and their length are inherently linked to the quality of service provided by the TSA, allowing private entities control over those lines allows those entities to control the quality of the TSA's service.
It the end, wouldn't it be fairer to allocate "elite" access based on the number of TSA screenings a traveler has paid for in the past year?
