There is nothing mythological (ie, fictitious) about imagining what Dublin was once like: a beautiful Georgian city, one of the finest in Europe; and the Custom House, one of its defining statements. This might read like romantic mush, but we cannot continue to defend the mistakes of the past and the present. With architecture, it is possible to correct mistakes, or flaws. Moreover, it is an aesthetic discipline. Therefore, I do not think it is a waste of time and money or unjustified to recreate a Dublin in which we can have pride.
