I asked you for a justification on why the states deciding to decide their electoral votes based on the national popular vote should only happen through a change to the constitution.

Your reply was that the constitution doesn't say that the USA is a direct democracy.

So, I explained that adopting the national vote wouldn't make the USA a direct democracy. I also explained that the constitution doesn't say that the states need to decide the electoral votes based on local popular votes only.

So, I refuted your argument in two different ways. I'm not sure where you feel I didn't respond to it.
