That seems orthogonal to the question of how desirable (or not) scrum is. You can have scrum (or not), and/or have "an experienced team that respects the other team members to plan their time and prioritize tasks" and shitty management is still going to wreck things.
A real and reasonable criticism of Scrum or Agile is, the structure is not helpful to the actual work.
I 100% agree that there are times when the structure imposed on a team in the name of Scrum (whether it's actually prescribed by Scrum or not) is harmful. Don't mistake what I'm saying here as a massive endorsement of Scrum. It's not actually my preferred methodology. But I do think Scrum can be useful to very many teams in very many situations, and I feel like a lot of the criticisms directed at scrum are somewhat misplaced.
If nobody is doing Scrum right, we're right on the edge of a No True Scotsman argument.
I think I get what you mean by that, and I probably agree to a point. But I don't think it's quite "No True Scotsman", as Scrum has an actual definition, to an extent that "true Scotsman" does not. But I'll buy the suggestion that "if everybody is doing it wrong, then there's something fundamentally wrong with the whole situation".
