Sometimes the expensive route is faster. Like taking the toll route to your destination. You pay more because you receive convenience in return. Someone invested heavily to create a faster alternative for you. You reward them.
Sometimes the expensive route is slower and harder. Like deciding to build a highway under a forest to protect it. In the short term, this makes no sense. It costs more, takes longer and does not decrease the travel time.
Sometimes we chose expensive, not for ease, but for a healthy future.
