Im also confused why you say China's inaction on Taiwan isnt about TSMC its about patience, but patience is running out because China wont need TSMC in 10 years. That seems to contradict itself.
It's easy to grow very fast when you are starting from a very low base. Especially when you are chasing someone.
It's a bit like China's GDP per capita. If it continued growing at the same pace as between 2000 and 2020 it might have had a chance to catch up with US in a few decades or so from now. Certainly Western Europe.
Yet based on current trends they will never close the gap (then again who knows what will change in the next 10-20 years or so).
Of course demographic collapse is not that far either. US and Europe at least have immigrants propping them up.
China is patient. They seem to be taking a long term, intentional approach. Their goals are long term. In other words, they’ve been planting trees for decades and those trees are now beginning to provide shade. Americans, in the other hand are more concerned with their own self interest and the next financial quarter.
Without going into the lack of military capabilities to mount the largest amphibious invasion post-WW2 up until recently (debatable), I think you’d be hard pressed to find a group of people in the world that would be excited at the idea of being put under foreign occupation (not dissimilar to the “excitement” the Taiwanese had to be occupied by the Republic of China after WW2).
Regardless, TSMC wouldn’t survive annexation Taiwan being annexed by China in any capacity
Do you think an invasion of Taiwan brings risk of a new, worse status quo? I think that's primarily why China doesn't invade. If it were possible to just achieve an easy, total victory then there is no reason to wait for Taiwanese people to change their mind about joining China.
In my humble opinion, if China wanted to, they could win it now. China's vast resources and manpower will be overwhelming. Doesn't matter if they lose a few battles or takes a few years.The reason China doesn't want to is because they want a peaceful reunification. They want to wait when it's so obvious that Taiwan would lose and lose quickly that Taiwan simply gives itself up.
I agree they prefer a peaceful resolution but that would be in the form of Taiwan wanting to become part of China and deciding to reunify. It makes no sense to surrender without being forced to.
The scenario where Taiwan peacefully reunifies is where they decide they want to be part of China of their own interest.
