Sure. I've never spanked my kids, but they do know how to behave.
I'd say natural consequences are an important part of my parenting style. If you make a mess, you clean it up. If you throw your food, the meal is over. If you misbehave in company, hurting or insulting others, you have to sit by yourself for a while. If you break it, you either fix it or (if possible) pay for it. If you use something irresponsibly, you lose it.
And of course the other side of the coin: if you are kind and generous to others, you get to invite friends for play dates more often. If you handle possessions responsibly, you may sooner get more expensive things, like a tablet. If you help around the house, chores get done faster and we can do something fun together.
My kids know exactly what the rules are, and what consequences to expect if they don't follow them. And while I certainly wouldn't claim they are perfect little angels, they do usually try to live by the rules.
