The goal here was stated as "prevent China from militarily taking control of Taiwan". It wasn't "occupy Taiwan/Beijing/wherever and deal with an insurgency".
The US left Vietnam due to lack of national willpower, not due to military defeat. Again, the problem statement here was formulated with "given a nationally united, determined US".
China, attempting to invade Taiwan and being met by the US military, would fare little better than Saddam Hussein's military did either time they went toe-to-toe with the US. The insurgency afterwards is not relevant to the discussion, as the US need not try to occupy China.
