The NYTimes had an article on an absolutely unregulated city in India. Sewage bumped in vacant lots is a problem. Safety outside developed areas is a problem. Still, removing parking requirements might be a good thing if creates incentive for public transit. Removing single family home mandates seems like it would be great for avoiding sprawl. But as you say, just these two. http://www.nytimes.com/2011/06/09/world/as…
You're making a massive leap from legalizing more different kinds of development in the US to a totally unregulated city in India. It's basically a strawman fallacy. The article clearly talks about a lack of many basic government authority and services way beyond zoning codes, like electricity and criminal justice. I think the lack of reliable power and sweage treatment might have a lot more to do with it being chaot…
The original comment: If you want to fix the country then remove all limits, let developers develop whatever and whereever they deem there is demand.
