Antitrust oversight of Google, similiar to what was done to Microsoft in the 2000s, will do more than spinning off any properties from Google.
Google is able to invest in and made Chrome popular using cash from their advertising business, and Chrome's popularity allows Google to shape the web environment for their advertising business. If Google were to lose Google Chrome, there is nothing that would prevent them from directly or indirectly evolving Chromium. If Google is prevented from making a browser, then they could even move the focus of computing away from the web browser with power from their search business.
Therefore, antitrust oversight is required to curb the types of behavior that lead to the antitrust situation in the first place.
