Rockets have the structural integrity of a pop can.

And yet pop cans travel halfway around the world daily... I don't see the issue. As I said, it could be expensive, but there's no risk or danger in it.

People transport extremely fragile things by sea all the time. You may have to be mindful of weather, but it is do-able with the will and money.

Empty pop cans? Several stories tall?

How many pop cans are damaged or destroyed in shipping?

Any rate at all is higher than is tolerable for rockets costing many orders of magnitude more.

REALLY?!?!

Your pop can is not filled up with tons of explosive materials and didn't cost millions of dollars.

The worse thing that can happen if your pop can is damaged is you get a flat soda or a leaky can.
