The main reason the Greek city-states developed separately was the terrain. Greece is very mountainous which made it difficult for people in different parts of Greece to communicate. Therefore city-states developed independently.
The earlier model was farming land with a citadel (acropolis) to retire to for protection. Around the citadel grew up houses, businesses and cultural venues, which then were walled in for protection. And this was a city - a place to live and its supporting agricultural land, usually handy to the sea or river.
Greece is made up of a main peninsula and many islands, and is incredibly mountainous. At the end of the Dark Age in Greece, people formed together in groups for protection. Each polis (Greek city-state) was so isolated from one another that they all developed their own form of government. For example, when Athens started democracy, not all other poleis followed suit. Some remained as tyrannies or other governments.
They developed independently because they were separate polises, and they had a lot of natural barriers. They often bought each other though. Each polis or city state had its own government, economy, and way of life but came together when there was a common threat for e.g. the Persian Wars which ended with Alexander the Great's conquest of Persia..
In the post-Mycenaean period the structure became an agricultural area with a town as its centrepiece - social, commercial and defensive.

The early Greek kingdoms developed through a process of cultural diffusion and assimilation, as well as competition and conflict with neighboring city-states. They emerged from smaller tribal communities and evolved into larger city-states with organized governments, economies, and military capabilities. Trade, colonization, alliances, and conquests were all factors that contributed to the growth of these early Greek kingdoms.
The city-states began to develop, leading to growing civilisation of the Greek world.
