Not at all. Building a subway in most US cities right now is very expensive. Raising the tax revenue alone is probably a non-starter.
Moreover you're going to have to close the road down anyway to do any form of cut-and-cover or even deep bore construction, which means every business on the corridor and every person who lives on it is going to get angry for as long as the subway is being built.
There's no painless way to do infill public transport. The problem is that nobody in the US is willing to compromise.

This is true but seems like a problem worth solving. It's also true of more than subways; we have the same problem with bridges, housing and many other things. Better to get on with fixing it than use it as an excuse for doing something worse.

That's a one-time cost, and you're not required to close a 500 mile stretch of road for years on end. Dig one block, install the tunnel, cover it, dig the next block.
I agree with you (and importantly you can't make a subway political football the way you can make a bus lane), but my experience doing transit advocacy points otherwise. Americans in dense areas are feeling the HCOL pinch and are not very willing to float extra taxes to fund transit expansion.
IMO it comes back to the fact that Americans are just not willing to accept change of any kind right now. The economy feels too shaky, the electorate too divided (even within states and municipalities), and there's too little faith in government to architect the kind of change you'd need to build subways, underground metros, or even BRT. We need a larger feeling of unity even at a state level to make the changes necessary, which is why municipalities continue to do bare minimum maintenance of roadways and pretty much nothing else. The last big set of constriction in dense urban areas was funded by the Obama stimulus from the GFC which was passed 17 years ago.
It was probably always a good idea to do it the other way around anyway: You don't start with transit, you start by building more housing. Tons of it. Then the cost of living starts to get back under control and the density increases some, which you need in order to make transit work regardless.
