Hey, I’m new to anarchism

I just have a couple questions, if you could answer them that would be awesome!

1: In a state with no government, how would you make sure crime is few and far between? 2: How would you motivate everyone to do their jobs without punishment or payment? 3: How would you defend yourself in case of war? 4: How would you engage in diplomacy and relations with other countries?

Thank you so much!
