Let me first check if I understand your argument correctly: You are saying that my argument is wrong because subsidies to something like agriculture while also not directly encouraging fossil fuel usage, can potentially increase the CO2 output overall. Because subsidies are changing (lowering) prices, so they influence the behaviour of customers.

I partially agree. If your subsidies are helping parts of the agriculture that are more polluting than the industry average, then you are increasing the environmental pollution.

But this does not apply to my argument for 2 reasons: 1. I am talking about bailouts. They rather don't influence the long-term prices of flights. They are one time thing, intended to help some companies not die. 2. Even the agriculture subsidies you mention I would not call "fossil fuel commitments", which is misleading. Better name for them is something like "subsidies that encourage pollution" or "subsidies that encourage increase CO2 emissions".
