Steve оwned аn 80-yeаr оld mоvie theаter building which he had purchased decades ago for $75,000.   Due to its age, the building was in dilapidated condition. Customers were deterred from seeing movies in the theater because it was located in a run-down part of town.  As a result, Steve was unable to convince film distributors to allow their best films to be shown there.  Steve planned to demolish the building.  But the city then adopted a “historic theater preservation ordinance.”  A city commission designated the building as the city’s first historic theater landmark because it was “the first movie theater in our city;” the commission explained that this designation would “attract tourists, help the local economy, and enhance the quality of life for all citizens.”  Under the ordinance, the owner of a theater designated as a landmark must maintain the building in excellent condition in perpetuity.  The theater generates $50,000 in total income each year; it will cost $55,000 each year to operate the theater and to maintain it as required by the ordinance.  An appraiser estimates that, as burdened by the landmark designation, the building is worth $20,000; it has a positive value only because of the possibility the ordinance might be repealed in the future, which would allow a new building to be constructed on the land.  The next oldest theater in the city was built five years ago.  Steve sued the city, claiming that a taking had occurred.  Which of the following is most likely?
