Just as in the definitions you cited, the word control has more than one meaning depending on the situation. That means that the "control" you keep bolding in the definition of nationalization does not necessarily mean the same thing as the "control" in the definition of regulation. Your entire argument relies upon both definitions using an identical meaning of the word control, despite logic and evidence clearly indicating otherwise.
This is likely why you have been utterly unable to come up with a source that says regulation is equivalent to nationalization.
I cannot believe this needs to be explained to you.
