I'm also German and I would like to have a general speed limit on highways.
Your theory sounds all nice and works if you drive on empty roads, but as soon as there's a bit of traffic the lack of a speed limit results in a very stressful and uncomfortable driving.
The main problem is the speed difference between the individual lanes. On the right lane you have the trucks which are limited to 90 km/h by law, so that's the maximum speed you can usually drive on that lane. Now most highways only have two or three lanes. No speed limit usually results in a difference of at least 40 km/h between lanes and always-changing speeds because of traffic. Driving in a small car with a low-power engine is no fun at all, your only choices are getting stuck behind trucks at 90 km/h or a constant speeding up, slowing down, switching lanes and pushing your car to its limit.
My personal theory is that this is one of the main reasons why German drivers are so aggressive. The drivers most in favor of no speed limit are usually also the most aggressive.
It depends on the Autobahn. I strongly felt what you described on pretty much any Autobahn around cologne where there always was a lot traffic and many on and off ramps. However, my ride usually would take me from there onto the 44(?) towards Paderborn and there was no speed limit and it was a joy even in an old Golf 2. There were very few on and off ramps and moderate traffic. My car would be able to speed up to ~220km/h over the course of several minutes, but it was so worth it.
