I disagree Ivan.  Those destinations often require a time committment that allows for greater flexibility.  For example, you can summit Denali in less than two weeks if you are lucky with weather etc but most climbers budget a month or so.  Same for Ecuador, Peru, Bolivia. 
  
Liberty Ridge, because of its proximity to a major metropolitan area, can be climbed in a long weekend if the weather cooperates.  Which also explains why Hood and Fuji are climbed in such droves.
