No flaps landings are fine if you're in a tiny as shit Cessna. You're small, you have less momentum, and you've got a shitload of runway. You're probably slower with no flaps in a Cessna than a 737 with flaps.
The big jets are landing at speeds of like 200 knots without flaps instead of about 145 knots with flaps. Say you're landing on a 3000m runway. If you're not braking, it'll take 29 seconds to traverse that length without flaps, but 40 with flaps. Obviously, that calculation will be different thanks to braking and where the plane touches down, but the point is if you're coming in hot, you're gonna want as much runway as possible. You could also overheat the brakes if you overuse them. And let's not forget: imagine if you have a flaps issue during a snowstorm and all the runways nearby are totally inundated with snow and ice. That'd be a shitty thing to deal with.
