Google tried something along these lines with Contributor ( https://en.wikipedia.org/wiki/Google_Contributor), which in it's first iteration would bid on your own ad impressions. It wasn't popular, partly because it didn't cover all ads (not every ad goes through a public auction) and partly because it fundamentally cost you money. They later tried another version, which only worked with specific partners but did exclude all ads; it wasn't popular either.

All Google ads. Not all ads.

Are you talking about the second version? That one did exclude all ads on participating publishers, because to participate you had to set it up that way
