Which is the most important freedom to have?

Which is the most important freedom to have? Choices could include, but are not limited to:
Freedom of Speech
Freedom of Assembly
Freedom From Discrimination
Freedom of Choice (freedom to elect representatives)
Economic Freedom
Freedom to Arm Oneself
Any others you can think of...

This should be addressed as "That which, if denied, would cause the most harm." Please explain the reasoning behind your choice. I honestly cannot make up my mind at this moment, but my hope is that this will spurn an active debate.
