I like freedom too. Currently, animal agriculture is heavily subsidized, so if the US quit doing that, people would eat less animal products. It would be better for the planet and more free as well.
We have a social contract going where, for instance, we don’t just kill each other. I’m quite alright with not having the freedom to heavily infringe on someone else’s freedom. So I do think it gets complicated when environmental issues are literally killing people. I’m in WA state, and the smoke from the wildfires last summer made everyone sick, and there was nothing we could do. I had to watch my normally healthy 3-year-old unable to breathe well, and all I could offer her was to keep all the doors and windows closed for over a week and not go outside. But we don’t have AC or anything, so there was no way to keep the smoke out of the house. Others’ choices were very clearly affecting our health. Nobody lives in a vacuum.
