Very indirect. They have requirements for driver's licenses being used as IDs for federal purposes. (Which is actually not unreasonable although we got by without doing so for many years.)

The issue of course is that their driver's license is the only government-issued photo ID they possess so if they want to fly or enter a federal building without a driver's license, they would need to get a federal ID such as a passport issued which has both monetary and time costs. (And isn't available for everyone.)
