I don't think you're thinking about this properly. There's no safety net for someone who wants to quit being amish. They are free to leave, but they do not have the capacity to fend for themselves outside of the cult.

I think the larger problem is that you don't have a definition of freedom. You throw the word around like it has formal implications, but I challenge you to present one example of "freedom" that does not end up being oppression to someone else.
