Sometimes you don't need a dry dock. I wonder just how big you can go doing this. Bath Iron Works does the same thing. In both cases they still need a floating dry dock to lower the ship into the water but I would suspect you don't need one to match the full length of the ship. I would think a submersible barge would work (I think that is how Austal in Alabama launches their ships).

Here is a video of LPD-24 "launching" from the same position. That barge to the left in the above picture is a submersible platform. The LPD weighs in at 25,000 tons and the LHA comes in at 45,000 tons. Off hand, there may not be a physical limit to going beyond this. Newport News is not going to stop being the only carrier yard in the US unless there is a major war. However, I would suspect that methods that build on level land might have more benefits than traditional dry dock construction.

good news, I suppose:
USS George Washington Concludes COE Evaluation
The Nimitz-class aircraft carrier USS George Washington (CVN 73) and its embarked air wing, Carrier Air Wing (CVW) 5, successfully completed a combat operational efficiency (COE) evaluation, June 5.

The COE certification, often called the “blue-water” certification, allows the ship and air wing team to launch and recover aircraft without the requirement of a divert airfield nearby.

The George Washington and CVW-5 team began their certification process May 28 and were required to meet established criteria of efficiency and safety during aircraft launch and recovery operations for nine consecutive days.

With COE complete, CVW-5 can move on to more complex exercises.

George Washington and CVW-5 are on patrol in the U.S. 7th Fleet area of responsibility supporting security and stability in the Indo-Asia-Pacific region. George Washington will conduct a hull-swap with the Nimitz-class aircraft carrier USS Ronald Reagan (CVN 76) later this year after serving seven years as the U.S. Navy’s only forward-deployed aircraft carrier in Yokosuka, Japan.
