That is a bizarre and incorrect assumption, but if you weren't trying to start a fight then you might have made the reasonable assumption that I think there are problems with the way adoptions work in the US as well, and if you want to adopt within the US you should still be prepared to put a lot of work in to identifying the ethical way to do so. Start with the assumption that you should absolutely not be planning to move the child to a different country or even state as soon as you've adopted.
The difference between us is that you are making an effort to jump to the stupidest possible claim you can think of, like here where you have managed to read "should not plan to" and twisted it into "should be prohibited from".
When you say that people need to be ethical, and then give your only example and say that they “absolutely should not...” I think it’s fair to say your claim is that it should not be done.
Meanwhile, we literally sell babies with impunity which we euphemistically call "surrogacy."
