How is it a strawman you clearly said that consumerism has no impact on climate change here:

Good for them for taking a stand against consumerism, personal shopping habits (even collectively, they equal less than a drop in an ocean) aren’t going to change neither climate change, nor inflation.

You probably did not mean it, but I thought I have to clear that up.

This “the big guys up top, have to solve the crisis” is just a way to deny any sort of responsiblilty and therefore ends up without any sort of action.

As for that, I have seen that way to often. Classic alternative to "but China".

Just look at some research. So when you want more solar panels in your community, a good idea is to install solar on your roof first. That makes you 63% more likely to convince others to do the same. This can lead to tipping points being reached, which have a much wider impact. At this point the movement can be used to change the underlying system.

You keep believing that, and continue to be completely non critical of who is promoting that notion to you and why

This is were it becomes important to look at what the campaigns actually try to do. BPs famous carbon footprint did try to make everybody understand that the y use fossil fuels. It did not lobby to stop driving and take public transport instead. Same story with many recycling campaigns. They go for throw it in the bin, rather then show you how to not use as much plastic. The key in those campaigns is not to show a viable alternative, but to make people feel helpless. After all, when there is a working individual action, people might lobby to make it mandatory and that destroys their business. BP does not run ads to buy EVs instead of ICEs today. That would be a viable alternative. So they promote the red hering of hydrogen powered cars. After all the individual action of buying an EV instead of an ICE can easily be scaled, by making selling ICEs illegal.
