I can explain it to you, but I cannot comprehend it for you.
Could you come up with some more specific examples?
You apparently cannot even handle the first example I gave you.
Ron Paul is anti-slavery also...so I guess he has that in common with Spooner.
Ron Paul also eats food and sleeps in beds, just like Spooner did.
What are germane are not the many things Spooner had in common with other people, but the distinct aspects of his political philosophy that differentiate him from other thinkers.
His differentiating factors are quite simply his advocacy of anarchism - and his outlining of specific tactics to be used in undermining the government of the United States and its Constitution.
Ron Paul eats and sleeps and theoretically opposes slavery (although he would be dead set against intervening in the Sudan to end it) - but more to the point he supports Spooner's tactic of using juries to deliberately undermine the Constitutionally-assigned role of the Supreme Court.
The autobahn was "one of the most intrusive government-funded public works projects in Western history?"
Quite a bit of valuable private land was extorted from German citizens for a pittance at a time when land values were at rock bottom due to the Depression.
The regime acquired enormous swaths of land for pfennige on the mark from people who didn't have much choice in the matter.
