What is the first purpose of having life be like a show?

The first purpose of show is to make life acceptable. Raw nature must be landscaped and formed into suitable forms and rituals to hide all that is ugly and unpleasant. Everything is better when it sparkles and has some form of order even if to exhibit fleeting control. The core of Italian belief is that life is catastrophic and its effects cannot be eliminated, only mitigated, so the passion for illusion allows them to glide over life's surface leaving the ugly part as untouched as possible.
