I could see the IRS offering some service to enter the market and compete with Equifax to bring more competition to the sector. They might have to compel Equifax to give up some data or data sources to the government and their competitors. The government did this in WW2, forcing companies to give trade secrets to their competitors so there would be a more resilient supply chain. Something similar could be done to break up big banking if the US Postal Service allowed people to open up super simple checking and savings accounts.
