I don't think the results would be much interesting. Lots of sites will be default homepage/about/contact, where the author never started the site. Then a ton of useless pages like auto-generated indexes and summaries, that humans don't care about. An endless amount of duplicates because query string ?arg=value can crawl infinitely. And last but not least, copies of major sites and spam pages trying to fill search results.

I personally made a few websites and in my opinion it is fairly easy to get indexed by Google. If you open a pizzeria in small city, should be trivial to be top result in google for "pizzeria in town" after a week.

Despite all the critics Google is incredibly good at finding readable relevant content.
