I doubt it plays out as simply as you describe, and there's a million ways it can play out depending on jurisdiction, etc. Likely, someone signs contract, comes to collect, Lambo says "Nonsense!", buyer says, "It's Binding!", and then the mess starts. If everyone's sensible, they come to a reasonable agreement. If not, it's "see you in court!", and everyone incurs costs of a trial, and the judge & jury impose a reasonable settlement (values of "reasonable" can be quite a wide range and often surprising). Lambo also likely sues and/or prosecutes the rogue salesperson to recover some token amount and mostly to make an example so no idiot tries that again. The result is a costly mess for everyone, likely preventing it from repeating (e.g., Lambo puts in more checks & balances), and life goes on. So, yes, consequences, not trivial consequences, and we hope enough that corrective action is taken. Just what we'd want done for LLMs also.
