Maintaining the original form of an old building is quite expensive. For this reason, I do agree that antique structures that hold historic value and can still serve their original purpose in modern society deserve more preservation than any old buildings that are merely iconic by design.
Although old buildings scream with prestige due to their impressive and nonpareil architectural design, it is important for governments, especially third-world nations, to prioritize pragmatism. Developing nations have many programs to focus on that require funding and resources than safeguarding all ancestral buildings, such as combatting poverty, malnutrition, and low literacy rates. Therefore, structures that were built fifty years to centuries ago, such as libraries, houses, hospitals, and commercial buildings that the new generation can utilize and not merely as a sight to behold, should be given more funds to retain their beauty rather than being forced to restore all old buildings.
Besides that it creates more jobs and generates more income, the young blood will expose themselves to the rich history of the building and encourage the feelings of national identity as they explore every room and corner.
As the government repurposes the historical buildings, these remnants of the past reflect the cultural and national identity of one’s nation. It also reflects the passion of the craftsmen who built these well-established buildings, as these survived disasters and wars. Furthermore, this can be an inspiration to those who aspire to build buildings that can stand the test of time.
On the other hand, all buildings with feeble structures that can no longer be maintained need to be demolished. Everything has its end and must be built anew with a modern structure. However, if the structure holds a historical rite, it can be renovated, but the government needs to seek a sponsor who can help them fund the complete renovation and not only rely on public funds. It should be someone who values more the history of the building than capitalization.
The preservation of old buildings requires money, effort, and a profound understanding of history. The government and its people need to decide wisely which old buildings can be and must be maintained for the preservation of history and the purpose of the building.
