Current account deficit already accounts for both goods & services. From a more formal perspective, deficts aren't neccessairly bad if they're being routed into productive investments at home, as with many developing countries needing to import machinery, but if it's being used to fund consumption, and it's persistent, then it's considered by many (including the IMF) to be unsustainable on the long term, and highly unstable on the short term.

The current account deficit can be also expressed as the gap between investment and savings, of which must be financed by a combination of private and public debt to external investment, of which around 50% comes from the ever-growing US Gov debt. You're basically going into debt to finance your consumption, and it's a big reason why the US credit ratings have been going down this decade. You won't fix the debt without addressing the deficit, and can you really count for growth to exceed the interest forever? When the black swan comes, then it's gonna hurt alot more than it needs to be.

Then you might have a bit of an "oh shit" moment as you realize that the industrial ecosystem required to substitute those imports would take a decade and a half to build even if your money were worth something, which it now isnt.

Lots of countries collapse due to overreliance on foreign imports. Argentina never recovered from its peak in the 1920s - it just kept bouncing from crisis to crisis. This is looking like an increasingly plausible outcome for the US.
