Fares exist for the sole purpose of discouraging use.

If you don’t want people to take the Metro from Bethesda to Gallery Place, then you shouldn’t build the Metro. But if you do want people to take the Metro from Betheday to Gallery Place then you shouldn’t charge them to ride. But if it turns out that your route is too popular at certain times of day, then you want to charge them in order to prevent overcrowding.Matthew Yglesias
