Barriers to entry/exit in Economics can be applied to an individual, however, when these concepts are applied, they are applied to a firm. That individual entrepreneur would be considered a firm in the market so I don't think a separate section specifically for individuals is needed. Also, barriers to exit don't really exist in a markets a solo entrepreneur could enter. This mainly exist in markets with high start up cost for manufacturing specialization ie: agriculture, planes, specific machinery.
