The cost to launch to space and back to earth for earth-bound cargo is not going to be remotely a thing in the next half decade. Nor the decade after that. Probably not ever unless we develop some entirely new physics for launches. Getting out of a gravity well is crazy expensive by mass.
Starships cargo capacity is 100-150t
A typical sea-going container ship has a capacity of about 220,000 tons.
You'd need at least 1500, possibly as many as 2200, starship missions to move the cargo of ONE container ship.
