Why is reefing so expensive?

Could you elaborate on the reasons behind the high cost of reefing? Is it due to the complexity of the process, the specialized equipment required, or perhaps the scarcity of skilled labor? Additionally, are there any environmental factors that contribute to the expense, such as the need for compliance with strict regulations or the potential for damage to the surrounding ecosystem? I'm interested in gaining a deeper understanding of the various factors that drive up the cost of this practice.
