&gt; After you sign something, it&#x27;s not important if it&#x27;s reasonable or not: you have to uphold it.<p>That&#x27;s frankly a ridiculous idea that clearly leads to injustice.  Contracts are often between people who are not equals, where one party has less ability to negotiate or walk away.  If the weaker party does not have extra protections outside of the contracting process, the stronger party could use its power to abuse them.
