The point is to stop people speeding in every location, so how does this achieve that?

The point of all traffic regulations and enforcement is to improve safety. Ensuring people adhere to the limits in high-risk areas does that.

And if the police focused their efforts in "high-risk areas" it would be hard to make the argument that speed enforcement is all about revenue.

They don't, so it's not.

That's a different tangent. Can enforcers abuse their enforcement privileges? Sure. Is the point of traffic regulations 'to stop people speeding in every location'? No.
