Sometimes you can't make choices. Sometimes, agendas are virtually impossible to meet in many cases, and even then, we have other issues that can undercut successfully navigating the agendas (like weird AIs saying we made promises not to move our units near their borders, and then saying we broke it when they move their units near, etc.) An agenda system which is nigh impossible to meet is just another wheel being used to crush the player (along with early AI aggression and massive barbarian horseman invasions 10 turns in).
