I believe that you will see the value of it when the company actually uses it and not something they are calling scrum. Tasks can’t be locked once they are not necessary anymore. The timebox idea of freezing work for a week is about “requirements” and not tasks. The goal is to have a somewhat stable target at least for that sprint. Working with stakeholders directly is one of the reasons agile methos were “created”. If you can’t collaborate with people who care and know about the project you are doing it wrong. The duration of the meeting or doing it or not is not set in stone. These are initial guidelines and the team should adapt once everybody is familiar with what they should do. Here is the thing, the basic layout of any agile process is to “teach” people to do what they would naturally do if they cared about their work: collaborate, work together on problem solving and help each other. Once that part is achieved, the initial process doesn’t need to be followed anymore as long as the values are kept. From your story it seems like none of that is being done and that why you see no value.
