How can you live anonymous? Off the grid maybe in a log hut in the woods. If you're in a vehicle, you'll need license plates. If you buy land there needs to be a name on the deed. You can obscure those maybe behind company names if you make the effort. But there will be a paper trail.
If you buy land, you might as well invest into a more comfy tiny house with solars on the roof and dig a nice pit for the toilet. Keep chicken and grow veggies or something.
We need a community for something like a banned on reddit therapy group. For people wgaf.
