Investopedia explains Free Rider Problem
1. A commonly used example of the economic notion of the free rider problem is found in national defense. All citizens of a country benefit from being defended; however, individuals who evade taxes are still protected by the same common resource of national defense, even though they did not pay for their fair share of the resource.

2. The problem with this scenario is that the client, if allowed to free ride, can profit from a stock trade without actually using any of his or her own capital. This is illegal.
