Actually, no. It doesn't work like that at all.
In most places, there are basically two types of written contracts that the law recognizes:
Negotiated - What you're thinking about, where you and another party have the ability to negotiate, haggle, and come to a consensus.
Contracts of Adhesion - This includes ELUAs, the contract between you and your electric company, etc. These *are* non-negotiable, take-it-or-leave-it contracts.
Seems unfair, doesn't it? There is a bright side.
Contracts of Adhesion are generally held to a higher standard than Negotiable contracts. If there's ambiguous wording, or a typo, or whatever, it doesn't matter, the courts take that literally, and the company or entity that wrote the contract is held responsible.
Basically, if in doubt with a Contract of Adhesion, the law will side with the party that had no choice. I'm simplifying things here, but that's the general spirit of the difference.
We use these contracts every day. No major provider of services would be able to do business without them. Public utilities, airlines, software vendors, schools, telcos, ISPs all use these types of contracts.
Dell is not going to negotiate with you on the terms of their wifi driver. Verizon isn't going to negotiate their TOU. Those things just aren't going to happen, despite how your mind extrapolated that "all contracts are the same!" when you learned about negotiated contracts.
But I *do* like how you spouted off like you knew exactly what you were talking about, despite not knowing very basic things about contract law. Well done.
