I related to this particular post by Michael Lewyn at Planetizen, Why I fight:
Occasionally, someone familiar with my scholarship asks me: why do you care about walkability and sprawl and cities? Why is this cause more important to you than twenty other worthy causes you might be involved in?
The answer: Freedom.
Now, the article doesn’t discuss freedom from a property rights or free-market point of view, but from a mobility point of view. As a former “carless teenager” in suburbia (well, carless until 16), I can relate to that. I think my yearning for freedom is what sparked my interest in the city too.
Of course, some people equate driving to freedom. For some its walkability, transit, or silent star filled skies. Freedom means different things to everyone, and I found my freedom in the diverse experiences and opportunities only available in the city.
