This might be a crazy suggestion but the most radical thing you can do in America today is live in an intentional community. After generations of pushing individualism (where historically your nuclear family could live on a single salary), we are now seeing how little safety or mobility we have on our own.
Living in community (depending on the type you join) would ease need for external resources (oh look you have a beautiful farm with fresh produce, eggs, meats, etc!), you're pooling resources and potentially income for the betterment of the community, you're receiving support raising your kids/ completing chores, the community itself has an income selling/ providing goods and services.
The ultimate protest for current society and the best thing for the environment as well would be for us all to live in smaller communities. We are a tribe species pretending we are not in this modern world and ultimately many things have suffered due to the individualism narrative being pushed as the only way.
