Why is star network expensive?

Excuse me, could you elaborate on why the star network is considered expensive? I'm curious to understand the factors that contribute to its high cost. Is it due to the complexity of its architecture, the specialized hardware required, or perhaps the maintenance and upkeep involved? Additionally, how does the cost of a star network compare to other network topologies, and what benefits does it offer that justify the expense? I'd appreciate any insights you can provide on this topic.
