That doesn't make it a coup. "Coup" has a definition, which is to unseat a government through illegal means, or to stay in power through illegal means. For example, January 6th could be considered an attempted coup. But just acting illegally a coup does not make.
One or two illegal measures would not be a coup, but if the president arrogates himself dictatorial powers, that is a coup. Trump is taking wide-ranging, illegal measures to fundamentally alter the nature of the American government. Constitutional rule very well could be coming to an end in the US.
