If it is a EULA, a rental contract on an iPad, or an employment contract delivered through DocuSign then I can't strike or amend any clauses I disagree with.
I think that's a mis-interpretation of 'meeting of minds'. The point is that when you sign the contract both parties are in agreement, but if either party is not happy with the agreement then they can either alter the terms until everyone is happy or they can simply not accept the agreement.
You could try suggesting changes to the agreement (e.g. with google when you sign up for an account), but they'll almost certainly just say they're not interested in making such an agreement. Perhaps if there was a few million dollars on the table they'd be more interested in adjusting the terms, but as it is they're offering a largely free service so most people have very little bargaining power.
Why not produce such a set of rules for consumer protection?
