Particularly in the case of Taiwan, the lawmaker speaks the truth. "...in intense situations, it may not face the risk of embargo.
Taiwan's status as an independent country is highly unstable. To a certain extent, it's built on sand. The threat isn't just any country; it's no less than it's superpower and bully neighbor: China. And it can't rely on other nation's help, too, even the US. The US could even betray and sell them to China.
If worst comes to worst and, God forbid, the tension escalates into a full blown invasion, Bitcoin is probably the safest way for them to keep their wealth.
They're sitting on tons and tons of gold that aren't even kept safe overseas. They're holding all of it in their tiny, threatened, island nation which is well within China's arm's reach. The lawmaker is right to warn that in times of regional tensions, "safeguarding these assets might become difficult." It's certainly a wise idea to keep some of their assets in Bitcoin.
China (mainland) is governed by CCP and they want to occupy Taiwan as soon as possible. They are still not able to do this but they have never abandoned their occupy plan against Taiwan. I feel quite sure that people in Taiwan are like people in Hongkong, they mostly don't want to be governed by CCP and live communist dictators. They are strong and want to fight for it but between want and achieve it in reality is big difference.
Taiwan proactively build up their own strength as preparation for any war with China mainland in future but they will hope that China mainland will have problems in economy so that there will be less budget for their army development.
Taiwan will aim at building up stronger economy and also army and this proposal is part of their efforts for a stronger Taiwan.
