To complete the 99th window, the king could simply order the seizure of all wealthy people's gems, demonstrating his authority. Although this could be used to complete the 99th window, it would actually violate the principles of property rights and personal freedom. The government and the king should protect people's property rights and freedoms instead of arbitrarily confiscating their property.

In modern civilized societies, authority does not mean the ability to violate people's rights at will. As a leader, one should set an example by respecting and protecting people's rights and dignity, rather than violating these principles to achieve one's goals.

Therefore, alternative methods should be sought to complete the 99th window, such as soliciting donations from the people or raising funds through other channels, rather than violating people's rights to achieve one's goals.
