The cost is admittedly going to be ludicrous compared to comparable projects anywhere else in the world.

But it's probably more just 'this is a thing that helps the godless commie city folk'.

I think the general arguments are noise and space required.

Though I fail to see how a train make more noise then a plane or tracks take up more space then a airport/runway.

They have been conditioned to hate anything the government does. If some company like Tesla actually made an effective transit system everyone would sing its praises, but if the government does it then that's socialism.
