Birthright citizenship is also constitutionally protected apparently, and this is arguably more central to the USA's historical self-perception but that isn't stopping Trump who believes he is acting in the USA's self-interest by blocking it. US also has valid, binding trade agreements with Canada and Mexico but that isn't stopping him from saying he will impose >= 20% tariffs or similar within the next week because again Trump believes he is acting in the USA's self-interest.
