Security isn't advocating something positive since it implies that you would need it.
Trying to accommodate irrational fears is often not helpful, it can even be abusive because you validate these fears. This is even a common mechanism to isolate people in abusive relationships. Don't go outside, there is danger in every dark alley!
Some other women might just try emphasize their vulnerability to fish for a protector. How evil of them, but hard to be angry about that.
If you always accommodate people for their comfort, you refuse them growth. As I said, it depends on the location. The locations that don't have the problem did not solve it by arbitrary security mechanisms.
How does it work?
So the actual process is dominated by "Does the project avoid X?", "Does the project ensure that Y cannot happen?", "Will the project ever exceed limit Z?" rather than "Does the project bring <positive-good> to its location?", because people have not yet agreed upon a clear definition of <positive-good> things. In contrast, the stuff to avoid makes itself known, and the stuff we can mostly agree on becomes part of our civic codes.
On the other hand, the heroin addicts don’t really have anything to lose, other than freedom to roam around the city. Since city is not interested in depriving them of that freedom (as jailing the homeless addicts for disorderly conduct would be inhumane, according to San Franciscans), it has no tools to actually incentivize different behavior — it has no punishments left, and so it’s left powerless.
I don't think government-bureaucracy-as-a-person-with-desires is a useful way to think or talk about this stuff.
IME, in Europe, the outdoor dining is usually directly adjascent the restaurant (in the US, it's often on the curb side of the sidewalk), though that is really speculation based on limited experience. Perhaps that is actually on restaurant property, and they set back the indoor structure. Or perhaps European sidewalks were built with that capacity in mind.
Also, perhaps the US, usually more restrictive with alchohol, has been less accepting of drinking in public. It doesn't seem like a problem to me, but then I hardly ever see anyone drinking in public. A city block with lots of restaurants and drinkers?

I find that is very rarely the case, especially for rules widespread across the country. Usually 'no good reason' means 'no reason I know' or 'not a reason I care about'.
