I agree with you, but that's how things work over here.
To stay on the topic of speed limits, there's a national speed limit for towns / cities, 50 kmph. It's usually not posted as such, but there being a sign with a town name means you must observe that.
Other peculiarities you have to know: when you enter a town, there may be a different speed limit posted than the national limit, typically 30 kmph, very rarely 70. It matters if the speed limit sign is physically attached to the name sign, or if it stands on its own. In the former case, it means that's the speed limit for all the streets of the town. If not, it's the regular limit, meaning until the first intersection, when the default one comes in effect.
While (as a European) I agree with your point regarding speed signs, I think an important point is that there are plenty of traffic laws that differs (even) between EU countries. So when going driving in a foreign country one really should look up at least basic rules beforehand, and speed limits will most likely be front and center.
Note that if you cross a border in Europe (not necessarily in the EU) by car, you will pass a sign [0] giving the default speed limits for each type of road.

The signs are otherwise identical.
