Mail-order sales of wine are illegal in some states. Some wineries argue that the ability

protect home-state wineries, raising prices to consumers. Others argue that the bans
allow states to collect tax revenues and to keep wine from being sold to minors.

A. reverse engineering.
B. a network externality.
C. competition to existing sellers.
D. a winner-take-all market.
