there's also the concept of a contract itself being invalid even if people have some right to enter it.

E.g. if you sign a contract while hanging off a cliff to give some dude all your assets in exchange for being pulled up, it is invalid in my jurisdiction.

Or if the people signing the contracts did not actually understand what they were signing it can be considered invalid (which would be akin to the mess in TFA).

Contracts are better left to people, rather then computers.

In Roman Law a contract requires consent, which cannot be forced, https://www.lawteacher.net/free-law-essays/contract-law/cont...

So it's not just your jurisdiction, it's probably at least half of the entire world and I imagine even systems not based on Roman Law have something equivalent.
