Well then, lets seize their land and vehicles. Then we put them in efficiency apartments co-located with government shops and rail stations.
Willie, being a benevolent dictator, will even give them free wifi (paid for with their tax dollars).

Depends what you mean by "spread out".
I bet California's population density is actually more concentrated in the metropolitan areas of San Francisco and Southern California, than any area in Germany. And much of the rest of California is more sparsely populated than anywhere in Germany.
I'm sure Germany also has differing population densities in different regions. But not as wide a difference as in California.
