What if Google didn't scrape websites automatically, and waited till users submit their domains to them, to mark that they want to be scraped? I think in that case, most users would still submit their domains there, because they want to come up in Google search. You might want your website to be scraped by some people/companies and not by others, but not have to put everything behind a login screen (which some determined scrapers would still try to breach in some way).
