The best they could realistically do if the invasion does succeed is try to force an embargo. This will be massively unpopular, kill tens of thousands in third countries that will be sanctioned as collateral damage, and crash the world economy, and still might not work.
The past 100 years of wars and military conflicts have shown that military logistics can overcome great distances if needed.
Great distances and economic consequences did not stop past wars. I doubt they would stop a war caused by the invasion of Taiwan.

The damage would be incredible, likely as bad as World War 2, or possibly worse.
Great distance stopped many, many wars. It is the reason the US is so rich, right now.
Economic consequences did not stop actual wars, yes. But in the event that an embargo is the only realistic alternative, it is a very powerful factor.

Yeah, the wars of German invasion of North America -- sub-theaters of WW1 and WW2 -- were over so quickly hardly anyone even noticed them.
I do wonder though: if that is the USs plan, why not say so? The US has formal alliances with NATO, Japan etc. They're public, because making them public dissuades the chance of an attack. If you're going to risk getting into a war, why not minimise the risk at no cost by being upfront about it? Instead the US maintains a position of "strategic ambiguity".
It would also be hard because China isn't Iraq. It's a nuclear nation with a bigger stronger army and much better morale. And Taiwan is an Island. You can't mass your troops 100m from the border and then march over when ready. The allies would need to do an amphibious landing less than 200 miles from the Chinese coast (aka air force), under fire from subs and against a fortified target.
Strategic ambiguity means china is emboldened and that Taiwan cannot rely on any US support whatever secret deals have been made no?
I am inclined to believe that it would look similar to Iraq invading Kuwait, only 100000 times bigger and bloodier.
I think the US, UK, Australia, Japan, and many EU nations would strongly disapprove and take military action.
