I think you're right about obscurity preventing a lot of low-grade issues.
There's an interesting building right in downtown Minneapolis that takes up an entire block that I'd passed several times a week for years without even noticing it—it's the operations center for Wells Fargo (and actually it just recently has been sold).
Zero signage and very nondescript, but when I found out what it was some of the physical security around it started to become super obvious. Big bollard "planters" and protection from large vehicles, a lot of cameras, no real obvious lobby.

This is the building, it's fascinating to check out the street view all the way around the block: https://maps.app.goo.gl/UYKnA2Bs9gMQsSwo9
