Anyway, there are bigger problems in the world than Google. While I am not sure payment processing is more urgent that regulating Google, there are many other things that are orders of magnitudes more important to tackle than regulating Google.
It seems inappropriate for regulation to step in when something happens to be popular but there are equal or better alternatives easily available, and changing to a different search engine is about the easiest change a person could make in their life.
In the case of mitigating any bad behavior by Google, there's a very easy alternative solution for the problem, which is to convince people to use other search engines. I haven't used Google as mine for over 15 years and I don't believe I've suffered at all for it. I've found DuckDuckGo to perfectly suit my needs. Google run as a public utility could potentially hurt all the other search engines that many would consider to be superior solutions already.
