I'm not talking about how efficient sea shipping is vs flying or driving.

Well I guess that was what made the original statement confusing, because that's definitely what it sounded like you were saying . I imagine this feels like a frustrating conversation (and I am sorry for that), but it's probably because of that lack of clarity.

I mean you said traveling by sea was especially inefficient, mentioning the huge waste of resources. I think it's reasonable to interpret that the way I did.
