You can drastically reduce related emissions by just giving up beef and replacing it witch chicken. IIRC it's something like 1/5 or 1/6th the amount of greenhouse gas emissions pound for pound of meat.

What you write is true but I don't think will be duplicable on a large scale without regulations and pricing negative externalities into products. The free rider problem is a negative aspect of human psychology.

The question is what someone who is aware of the issues and willing to act can do. Just because there are those who act irresponsibly does not prevent you from adjusting your behavior.

It does actually prevent me for adjusting my behavior. I'm a victim of free rider thinking. I'm not going to fall on my sword so to speak and sacrifice whilst almost no one else does.

Please reflect on what you are saying. You stylize yourself as victim when you are actually benefiting from making harmful decisions and then rationalizing that harmful behavior with "but everyone else is doing it too".

I haven't stylized myself as anything other than a person who advocates not having children. I over consume. I've come to grips with this fact. I deal with it by not having children as a means of assuaging my guilt. I've got just one life and I'm going to enjoy it as much as I can. I'm not going to sacrifice for the greater good when it's just me and a handful of other people doing it.

Why not invest in space-faring companies? There are 40 billion earth-like planets out there. Plenty of room for lots of different eco-systems to flourish.
