I find your tone insulting. No, sorry, your word is not the end of anything and other people may disagree with you. Even if everybody agrees with the statement that “China cannot threaten Taiwan without a huge navy” that is not the end of any discussion. You seem to imply China does not have and can never have a huge navy. And why can China not threaten Taiwan with missiles or even nuclear bombs?
That is totally unrealistic and it is never going to happen. No way. You might see a small unbalance but never that much. And a small unbalance is not going to have any appreciable effect in anything.
In the USA there are plenty of people who are single just because they did not find the right person or because they prefer to be single. To the individual it makes no difference whether he did not find that person because that person does not exist or because she exists but he could not find her. The fact is many people are quite single and lead happy and fulfilling lives.
A man might want to marry Sandra Bullock but he might settle for something less. Women live longer than men so there would always be older women available.
Men usually marry younger women so all you have to do is decrease that average age difference by 2 - 3 years and you are increasing the potential brides by much more than any unbalance in sex ratios.
There are plenty of single women and men in China and everywhere else and the reason they are not getting married is because they don’t want to, not because they can’t.
