Do I routinely need a compass? No. Do I routinely have a compass? Yes, when in the back country (always). No, when in populated areas. I actually have quite a few compasses. Baseplate compasses, sighting compasses, lensatic compasses. That's because compasses are just plain cool and fun to play with.
I will admit though, that where I live all's I have to do it look towards the mountains. That is west. Good enough for navigation in populated areas. And when hiking in the mountains, it is almost impossible to get lost here. To get out of the mountains and back to civilization, just go downhill. Unless you climbed out of the drainage you are in, going downhill will put you right back near your parked car. It you climbed up and out of a drainage and down into the next one over, you'll know that.
What scares me about getting lost is ending in in a heavily wooded flat area. You don't have any high mountains to sight on to get a fix. A flat desert is similar, but you usually have a long line of sight there, so it's slightly better than a dense forest. Super scary would be to be disoriented in a swamp in the middle of nowhere Florida. I'd definitely want a compass there, and also I would have looked at maps to have an overview of the area where I was going so that I'd know which direction to head to get out.
In the mountains, there are plenty of tall things you can take a bearing on to triangulate your position on a map, assume you are well practiced with topo maps and can match something you can see to contour lines on the map. You also need a map of the proper scale so that things you are seeing are indeed on the map you have with you. When I was a little younger and did a lot more hiking, I would shoot a few bearings and triangulate my position on the map at every rest stop. Not because I was lost, but because I wanted to practice my compass skills. Then I'd pull out my GPS to check the accuracy of my triangulated position. It's better to have a compass and map of the area and not need them than it is to need those things and not have them, or not know how to use them.
