A large part of Agile, at least from what I remember in my ScrumMaster training, is to recognize reality.

You estimated that you would do x amount of work. You only did y. Or, you did x + z - wow, you are a great performer. You should verbalize your success more often.

A part of confronting reality, is confronting the prospect of under-performing employees.

I think your 'ideology' is blinding you a little bit OP, at least - if you want to base your concept of standups based on how they were formulated in the original Agile manifesto - 'At regular intervals, the team reflects on how to become more effective, then tunes and adjusts its behavior accordingly.'

Frankly, most dev teams don't give a whit about Agile and just do stand-ups to keep the PMs and SMEs appraised of progress and to check in on a couple of things here and there.
