This is because TCP expects an acknowledgement from the target address and a persistent connection. Were the target to be a broadcast, every node receiving the broadcast would have to reply, and the node originating the TCP broadcast would have to open a connection for every destination. Imagine trying to receive several thousand ACKs at once, every time data is sent out.
