It’s a shame how dead the Constitution is.
Conservatives who are now engaged with a ‘depends-on-what-the meaning-of ‘natural-born’,-is’ in order to get what they want, are really acting no different than the MarxoFascists who say the Constitution needs to ‘change with the times’.
Most of us understand the intent of requirement is that a presidential candidate MUST be born in the country to two American parents who are citizens. They were concerned about anyone having dual loyalties to ancestral nations being the Executive power.
Since Obama has set precedent that a candidate for President is qualified if their mob says they are, without any vetting or proofs beyond forged documents - then technically Putin could run for president.
I'm not sure where you get the "most" part of this. Quite a number of conservatives, myself among them, believe natural born means citizen at birth. As opposed to a naturalized citizen.
However, for purpose of discussion let us assume your definition is correct. It is profoundly obvious that many millions of impeccably natural-born citizens, by your definition, feel no loyalty to America.
So the requirement, by whatever definition, has failed in its purpose. I don't think even technical violations of the Constitution should be ignored, but the notion that natural born citizens are more loyal is just flatly untrue in today's world.
