fr breaking things and making them not unfunctional is not the same as drawing on them. you make a great point. I really doubt that most of the people writing here have ever even painted the outside of the building they live in. We don't actually choose any of these things. But if we all DIY customised everything, we would actually have more agency. And I love seeing evidence of actual public interaction with things around me.
My university for example, in every single room, every single table is scribbled on and marked for years and years. When I arrived there as a fresh faced student I saw scribbles that were 30 years old. Some people left their names, some people said they didn't like professor X, some people left Maxwell's equations on there. I'm so glad the university didn't consider it vandalism. This could be applied to so many more things. It had zero negative impact on my education or experience in the classroom, so how can it be considered vandalism?
