Human civilization is fairly short-lived and having undergone several wars, humans have only just begun to understand that democracy is a more acceptable social system.
Taiwanese voted for a reliable and trustworthy government so that they do not have to worry about food safety, security or the quality of healthcare, and least of all eggs.
Even if there were no eggs on the shelves for a few days, people would not panic, because they know they are living in a free society, and that eggs would be back on the shelves as soon as the government responds to the shortage. After all, eggs are not everyday essentials and any food that contains amino acids can be an alternative.
