There are regulations for agreements. In Germany for example, when you rent a flat, the customers have inalienable rights that he can't legally-bindingly forfeit even in written contract form. There is no such thing as a fully free market, and that is a good thing. The complaint is not that they want to control every detail. Certain parts of the agreements might simply not be valid just by clicking a check box, or the parts are not displayed in a form that is considered appropiate. Imagine a document with 15000 words that is unnegotiable by you. Will your mother read that so she can give meaningful consent? I don't think so, so the consent isn't valid. This line of reasoning is about common sense, and not about formalities, and I'm glad it is relevant in law.
