No one will click on the source, which means the only visitor to your site is Googlebot.
That was the argument with the text snippets from news sources. Publishers successfully lobbied for laws to be passed in many countries that required search engine operators to pay fees. It backfired when Google removed the snippets from news sources that demanded fees from Google. Their visitors dropped by a massive amount, 90% or so, because those results were less attractive to Google users to click on than the nicer results with a snippet and a thumbnail. So “No one will click on the source” has already been disproven 10 or so years ago when the snippet issue was current. All those publishers have entered a free of charge licensing agreement with Google and the laws are still in place. So Google is fine, upstart search engines are not because those cannot pressure the publishers into free deals.
This has already happened and continues to happen.
