> this is a first step, but its a step to disjoin the incentives of farmers and consumers on the ballot.

How does this disjoin? Assuming it becomes popular, wouldn't both parties be in favor of future legislation to remove the carveouts?

Consumers won't feel the pressure, so there will be less solidarity and therefore less political will. Very nasty manipulation tactic.

See also Medicare offering significantly more healthcare for old people, removing them from the pool of voters motivated to pass Medicare for all type legislation.

Lots of examples of “cracking” the voting population to stall political will.
