Okay but this also doesn't absolve you from your responsibility. At some point you're going to make a decision about where your personal boundaries in weighing your options are. And if you're not driving and eating (a lot) less animal products you're further ahead of the curve than others. But deciding when you find things unsustainable, it is still another decision.
Most people don't feel or don't see a positive difference from their choice. So they let go of their responsibilities because of it. If there is no positive impact it doesn't matter what they do, is their thinking.
While when you look in the supermarket now compared to ten years ago... Meat substitutes, vegan products, plant milks are abundant. So, things are changing, the choices people make are influential. It just isn't immediate. But even within capitalism the market is responding to changes, from the personal choices of people like you and me. It's slow and tedious, but things change.
Look I share the same frustrations. And true change can only come from political actions. Laws, oversight, fines, taxation, enforcement... Leaving change to the market isn't a solution to anything. We can't consume our way out of this problem.
But that's also not the point of our conversation, I'm trying to make clear that as a consumer you still bare responsibility over what you consume.
The problem is when people throw their hands up and just 'get what they need' mindlessly. That's also a choice.
When we can make choices that are clearly better and more ethical, we should. So it is on us to do the best we can, within the system we find ourselves in. We should strive for systemic (political) change outside of consumption, as well. One doesn't get nullified by the other.
