Earlier quoted context omitted.
> You can’t sell yourself into slavery or sign away your freedom of religion or speech. is this because of court rulings or explicit in law?
The 13th amendment in the US makes slavery illegal except as punishment for a crime. 1st amendment rights have been asserted in case law.
i wonder if it would be worth it to have an amendment that said "no constitutional right can be abridged whether by coercion or by choice"
it sounds almost whimsical: you have all the freedoms except the freedom to give up your freedoms
