I feel like you are all over the place. Or maybe just two places. Those two things:
1. We can “save the planet” (whatever that means to us) by forcing companies to change: ultimately it is we who have to change because the change flows from us
2. None of this matters: it’s just about personal integrity
Because these two can be combined: if everyone just had sufficient integrity/character then we could “save the planet”. We wouldn’t be trying to do that, as individuals, but that would be the emergent result.
What I’ve been complaining about all along is just the apparent idea that we can help the environment by voting with our wallets. But if this is all about (2) then I don’t give a shit at all: I don’t care about the personal finance aspect, the frugality aspect, or the “living your values” aspect; I simply think the idea that we as consumers have more power than companies is wrong. And specifically when it comes to “saving the planet”.
But if “saving the planet” is not a concern then we are just talking past each other.
And all of that crap about “excuses” is just you projecting your living-your-values mission onto others; I don’t care, for even one second, about that stuff. At least the way you present it.
It is, by the way, funny how you think that “companies” want us to think that we are powerless. Well sure, maybe they do. But they have indeed invested money in the idea of the all-powerful consumer. The now famous “carbon footprint” was an invention by British Petroleum: the idea that we should, as individuals—always as individuals—just turn off the bathroom light and maybe not drive on Sundays. The “carbon footprint” is of course the fault of individuals, not of entities like BP. British Petroleum and you would at least agree on that much.
Maybe the perfect consumer (as far as companies are concerned) does feel powerless. But she also has to feel a sort of paradoxical guilt for using about ten planets worth of resources (if extrapolated to the human race).
And yet another trick is to reduce people to consumers (as in only that). Hence your fallacious conclusion that my line of reasoning is that people should feel powerless. But that ignores the fact that people are also citizens, and they have more potential power as citizens (political animals) compared to your don’t-tread-on-me code of conduct.
