editable box under terms and conditions

I don’t understand why there is an editable box under terms and conditions to give customers the chance to type ‘agree’ or ‘disagree’ to the website terms and conditions. I’d rather this box wasn’t there and if there is no way to hide it how do I work around it so nobody takes advantage of this?

Is there a way I can,,

remove it

or

disable people being able to type in it

or

type above the box..do not type in this box/ typing in this box makes no changes to website t&c’s

I don’t see the point in the box and can only see it creating problems by giving the buyers an option to say if they agree or disagree with the t&c’s. Any advice on what to do with it?

Thanks
