I do wonder whether the Amish would take converts. There are certainly communes around that would. And yet, here we all are.

Granted, here we'd still be if half the population was voluntarily leaving modern society.

Nevertheless, you are still free to do it. Maybe join the Amish, for starters (although afaik they don't shun all technology).

In any case, you can get together with a group of friends and live the way you imagine. There are enough people who dream of that kind of lifestyle, that you should be able to find a group that is large enough.
