The point of regulation isn't for the state to turn a profit. In fact, I'd go as far as to say that regulations that drive a monetary profit for the state are generally bad because they create a perverse incentive. For example, municipal governments adversely affect traffic flow by lowering speed limits because those lower speed limits generate more ticket revenue.
You're right that the point of regulation isn't to turn a "profit" but the laws of economics always apply. If you have a fine of $100 for a widespread practice that costs $1,000 to collect, the state isn't going to magically allocate resource to applying it.
You could create a private right of action for this, but that is its own bag of worms.

I don't know about the US because the US is weird, but:
* at 30kmph the rate of fatalities in case of a car hitting a pedestrian is basically 0%, at 50kmph I think it's 5% or more
* at 30kmph collisions are much easier to avoid due to the increased reaction time and the decreased braking distance (I don't remember the exact numbers)
* at 30kmph you can hold a conversation at normal speech levels next to a moderately busy road, at 50kmph you will have to shout (and not even notice it due to the high ambient noise)
Etc.
