PUBLIC GOODS argument - private sector would not provide
Non excludable and non rivalrous but most is actually excluable like toll boths, but light houses are not

Firms would overcharge, a single seller can raise prices at will. However if you charge too much there will be competition, from either substitutes or competitors who can now compete. Regulation creates barriers to and creates monopoly
