OMG or we could somehow figure out how to get the federal government to "just"stop subsidizing corn.

Same effect as the tax (it would allow the actual price of meat to rise closer to what it should be), and VASTLY less coercive and prone to being gamed by well-lawyered insiders.

Ending the corn subsidy ends the indirect meat subsidy. It would allow so many problems to start self-correcting.

I agree with others - a tax to make food more expensive is inhumane and immoral. Please update your view on red meat.

Taxes ("sin taxes") disproportionately hurt the poor and financially constrained.

That you're even suggesting making meat 7x more expensive shows that you're not remotely concerned about your ability to provide food for yourself.
