Do you see how that position is 100% inconsistent with your original argument? By the logic of your original argument, a US company hosting a site for a US customer should be able to completely ignore UK law. But your original argument was that if they did so, they have no right to complain if that causes bad things to happen.
You wind up having to argue that every hosting provider everywhere in the world should take note of any content they may have that might be deemed unlawful or inappropriate in any jurisdiction and somehow segregate it. That's the total opposite of "each different country should be to follow its laws", that's, "everyone has to follow every country's laws".
