I see a lot of odd ideas in this thread.

Monopolies - If there are 4 ways to get to the airport and someone comes along and creates a 5th way that some people like better, that isn't a monopoly on travel to the airport. There don't need to be two competing tunnels, just alternates.

Existing public transit will shutdown - Loop to O'Hare is a niche market. Even at 15 minutes, is someone in Wicker Park going to go into the loop to catch this tunnel rather than head directly to O'Hare? No one in the Loop will ever want to go to Logan Square?

Eminent Domain - Strange to be concerned about private companies when government has been the biggest abuser. I fail to see how Musk could do more damage to the urban fabric than the interstates did as they bulldozed their way through the city.

Tunneling under the "undesirables" - Is this an argument that transit needs to be more egalitarian. Is it wrong to get on the interstate and speed past all the little farm towns instead of driving through each? Is it wrong to get in an airplane and fly over whole states rather than drive through? Maybe some businesses would feel they lose a potential sale, but most people either shop close to home or seek out a retail destination. Most people don't wander the city hoping to just run into a store. They use their phone and seek it out.
