It's also totally natural to sit on art, if it's convenient for sitting, even if it's many centuries old.
A decade ago I moved to California, and it's a very stark contrast there. There is so much greenery and similar that is just "off limits" and made for just looking at it.
Generally, in California things feel much more "fenced off", even without any actual fences.
However, one of the main parks has similar areas where you get 10s to 100s of people an hour, or people covering it up for extended periods of time for picnics, etc. If population was all that mattered, the park would be barren and the path would be lush, rather than the other way around
That is simply not true.
Nice to have a beautiful patch of grass. Even more beautiful and nicer if a few well placed interesting AND sittable rocks make it useful for tired people.
Endemic rule breaking can be "tragic" or the most honest feedback.
