From what I have come to understand sea based goods transportation isn’t nearly as subject to the political whims of a nation as land based travel. That’s one of its main advantage sis that even if say nation A has an issue with nation C nation A can still sell goods to nation B without issues of C blocking their travel With land based transport, it is wholly dependent on a nation state to be cooperative. Thst isn’t to say it wouldn’t be a solvable problem and I think generally most nations would see the benefits quickly but it only takes say the Russians having a fallout with the US (I’m the case of ever building that mythical Alaska to Russia bridge in the Bering sea to interconnect the continents) for them to cut someone off. Or let’s say a middle eastern terrorist group decides to blow up trade tracks that lead from China and great Asia into Europe. Most of that political strife is safely ignored via sea trade. Honestly I believe that’s what holds back globally connected rail which I think has a cheaper long run cost and could more reliably deliver goods in a perfect world I don’t have sufficient research to back this up at the one time though I simply just remember reading about this a few years back
