If you don't believe that people should be able to sell themselves into slavery, you should start by offering your list. If you do believe that people should be able to sell themselves into slavery, then unlimited freedom of contract is a basic freedom for you.
What you shouldn't do is pretend not to understand.
I'm not the one making a positive claim. I haven't even claimed such rights exist so why on earth would be the expectation be that I list them? You've assumed that I believe in this shared fiction.
We sell ourselves into a form of slavery every day. Some would argue that is a big driver of our current society and way of life.
