You could use that argument to argue against any regulation of any monopoly.

"You don't like that Comcast is going to decide what sites you can see? Then make your own ISP"

"You don't like that the water company is pricing people out of drinking water? Make your own water utility"

"You don't like that Golden Gate jacked their prices? Build your own bridge"

BTW, those examples aren't exaggerations. I imagine they're all no less difficult than making a new search engine to compete with Google.
