[Star Wars] Why would one use hyperspace lanes in hyperspace travel?

Everything I've read about hyperspace travel talks about how hyperspace lanes are important. Yet much of the time we see hyperspace travel, it is used wherever convenient. 

So my question is, what is the purpose of hyperspace lanes when they are obviously not necessary?

Most of the time people jump to hyperspace in the movies, they are following hyperspace lanes. The reason those lanes are important is because they are charted and regularly updated, jumping blind means you could crash into a star or other obstacle and have your atoms scattered across the galaxy.
