That’s not what I’m saying, I’m saying the act of “not buying it” (even if it was a complete and total boycott) has no impact on the production due to the system of subsidies, futures, derivatives, etc. that is set up explicitly to make sure production continues. And therefore has no impact on land/water usage, suffering etc.
With the point being that it’s a good first step, but if your expectation is it will change anything without first changing the underlying system you will be very disappointed.
