Take a chopstick or straw and stand it vertically like a model of a column, you push straight down from one end the line of force you exert travels directly through the core to the other end. Now imagine the same model column with a significant bend or bow in it, the force you exert on the top still points towards the bottom, but the force no longer travels in a straight line between the top and the bottom, how can it there is nothing but empty space there!
The amount of bow and magnitude of force needed to deform or collapse the columns depends on the materials and rigidity, but none are infinite.
