SH, as a cattle producer without market power, you can sell your cattle any way you want to.  No one, including myself, has limited you in this position.  Packers with market power may have different rules, however.

Quite personally I don't care if you can sell your cattle to the Angus Gene Net with Swift and "Bid the base price" or  sell in the cash market.  If you wanted to sell your cattle to the "my neighbor's high priced likes me as I am market" that paid a dollar a lb. more than the places you mentioned, no one is trying to take that right away from you.  Why do you confuse your right to sell ANY way you want to with a packer's limitations due to market power?  I guess you like confusion.

No one has limited your or any cattleman's options.  The packer's options may be limited due to the fact that they have market power.
