This is honestly the most important thing IMO. I don't really care that these people put themselves at risk, that's their decision, but making a wild animal used to humans or even depend them can be detrimental to the wild animal, the ecosystem, or the neighborhood. It can be harmless, but as you say it can go wrong very easily just because these animals change their behavior accordingly. They can endanger people and themselves and destroy property, like you say, but also might stop being able to get their own food. I don't know enough about the local ecosystem and the animals living in ut, so I wouldn't presume to try and change it.

For example, some friends lived in an area where the invasive grey squirrel population was growing and forcing the native brown squirrel population down. They would be seriously pissed when they saw people facilitate them, because that way they were contributing directly to the reduction of the native brown squirrel population. They don't know any better, but that's why they shouldn't have been doing it in the first place.
