Agree and disagree with the article. Was an intern at a local governance, Americans with disabilities act (ADA) office for a year. It was a city with history, and not a very good city planning at the start. Yes, need to compliance, reality is, it is very hard. Like you built everything on top of a single MySQL and then facing the scalability challenge so you will need to re-shard every other 6 months - and worse, as re-architecture a city faces much more complex problems.
