Imagine you run a company register for a local government. You want to let people look up companies by their registration number (which they must disclose in all communications to you) to see if they're legit and whether any warnings have been raised against them. You don't want unscrupulous marketers to just be able to `SELECT * FROM companies WHERE type='nail_salon' AND city='london'`.

If you aren't super strict about scraping, some shadowy business in Neverland, completely unconcerned with following your laws, will build that database.
