Your sibling moving pots sounds familiar, mine does that with my herbs.

Regarding the point about blurring acknowledging privacy but claiming control, that's an interesting perspective, but it might overcomplicate the intent. In collaborative settings, I've found such quick edits are usually about courtesy rather than asserting authority. Choosing to blur preserves the visual continuity of the sketchbook pages, which can be crucial for an authentic tour. It likely stems from a desire to share the process while being vaguely considerate, not from a nuanced power dynamic.
