Settlers wanting to argue the crown or queen had no say either have no idea of the relationship between the crown, queen & 'Australia', or they choose to believe an innate benevolence where the queen would have cared but somehow didn't know. If so, points off for job performance.
She had influence over the 'commonwealth'. Her wealth is not just ceremonial, and it was not acquired passively. It was built on the pain and suffering of Indigenous people. That was the plan all along and that's the plan that she was an agent of her whole career.
Demanding Indigenous people be respectful about the passing of someone who intentionally made our lives worse is outrageous. It's worth considering what she *could* have done - and didn't - to effect change.
