“Inalienable Rights: Part I The Basic Argument” - the liberal theory that both Nozick and Rawls missed
https://www.ellerman.org/inalienable-rights-part-i-the-basic-argument/
“An inalienable right is a right that may not be ceded or transferred away even with the consent of the holders of the right. Any contract to alienate such a right would be an inherently invalid contract, and, vice-versa, a right such that any contract to alienate it was inherently invalid would thus be an inalienable right.”
Notably, inalienable rights were not just a catalog of personal views like when people say that people have rights to healthcare. Rather, there is a theory that illustrated why people had these rights based on principles. It wasn’t just an assertion. They showed the institutional fraud inherent in contracts that alienated those rights.
The theory is still very radical even today if you consider the application to modern institutions towards the end of the linked article @neoliberal
