China's production capacity is exactly why they have to break the paradigm. Even full funding toward the manned-NGAD element would not change the equation.
If you want to stop China, you have to be able to make the price too high. We cannot currently do that. Any protracted action and we run out of everything including missiles and bombs in a matter of weeks.
You need mass. If you can't produce ordinance faster than you can shoot it or produce NGAD, F-35, etc faster than they are destroyed in the air or on the ground, you're screwed. We cannot do that. More complicated and expensive NGAD doesn't change the equation.
We need to build off new first principles if we're going to right the ship.
