If we want to stretch analogies beyond sense, how about this.
You walk into a cake shop that has cupcakes with names written on the icing:
You say "Can I have a cupcake with 'Iain' written on it?"
They say "200 OK, here's a cupcake with Iain on it."
You say "Can I have that wedding cake?"
They say "401 Unauthorized, Sorry that's someone elses' cake." You don't get a wedding cake.
You say "Can I have a cupcake with 'Alice' written on it?"
They say "200 OK, here's a cupcake with "Alice' written on it."
You say "Can I have a birthday cake?"
They say "402 Payment required, That'll be $15" You don't get a birthday cake.
You say "Can I have a cupcake with 'Bob' written on it?"
They say "404 Not Found, sorry we don't have any cupcakes with 'Bob'."
You say "Can I have a cupcake with 'Carol' written on it?"
They say "200 OK, here's a cupcake with 'Carol' in it."
You say "Can I have a cupcake with 'Dave' written on it?"
They say "200 OK, here's a cupcake with 'Dave' on it."
You walk out with 4 cupcakes.
Then the cake shop owner comes out and says "You stole the three cupcakes! I didn't intend for you to have them!"
Did you do anything wrong? Do you deserve to go to jail for it?
