It is possible to buy a car in less than an hour, though I agree that you can't buy real estate that quickly. New Yorkers might be able to pull off stocks, if the money comes to them while the NYSE is open, but I'm not in New York (or Chicago, for the Mercantile Exchange, or...)
It's kind of a bizarre question, though. I have several small business owner friends. Could I get them to mark up a croissant to $1M, with the understanding they'll cut me in on the revenue?
If not, then what really are the terms of the question? Arms length transactions only? How will that be adjudicated?
Similarly, if the Earth can't survive Exxon, it was never going to succeed in the first place.
I just have to keep on hammering this point, because it pisses me off so, so much. Many people seem to believe that, since regulatory bodies can be captured, that regulation shouldn't be done. This is called learned helplessness, and it's something malicious people inflict on people they want to exploit.
It isn't sticking your head in the sand to resist assimilation by an evil corporation.
