Designing a ship that’s too big to be handled by the ports.
That’s like building an SUV that’s too wide for the highways.
Not exactly the same. Those 16 ports that can handle these are likely quite busy ports taking a constant flow of container ships between them.
A few of these will stay busy. Just like a few of the Ultra-Large Crude Carriers can visit few ports but go to those few constantly.
Maersk has already awarded the contracts for larger ships.

During World War II some German tanks had to have their tracks removed when loaded onto flatcars in order to be able to go through the train tunnels in Europe. Too wide. The Tiger I comes to mind.
We’re gonna need a bigger port..............
