Have you ever been to Germany? one of the safest countries in the world, never had any issue with safety there.
And going back to your main point, yes, your whole argument is loaded and plain false. I grew up in high rises and it is perfectly fine. Usually you find variety of size, between 1 and 4 bedrooms the most common. The outside is actually very kid friendly, with a garden and a plaza where children can play while parents sit in a cafe. Also the newer developers are indeed pretty nice and very desirable, outpricing older ones.
Have you ever been around German 20 story apartment complexes? I have and I can tell you it's not pretty.

3 bedroom apartments in German high-rise complexes are a rarity. I never heard of 4 bedroom apartments except for the very rare penthouse or designer building. The standard here is definitely 2 bedrooms with 3 being a luxury.
On the flip side, we need to allow housing that is not a "forever" home, and in fact there is no housing possible for me that will be suitable for all stages of my life.
Santa Cruz is a university town. Most people are there temporarily until they graduate and find their real place. Population of 62k, half are students: 20k at UCSC, 10k at Cabrillo College.
If you're lucky, doesn't mean you can't have it both ways but it's just not in the cards for everyone. So most people have a choice, good job and maybe slightly higher standard of living in the city or a house further (or far) out with lower chances of good employment.
Also depends on the definition of "high-rise", the ones shown in the article are 5-6 stories and not 20+ soviet- or banlieue-style "blocs". Many nice, safe but not necessarily very cheap parts of Berlin are in that style for example. Plenty of safety and families, just not as much space as a proper SFH.
Keep in mind even in America most places don't have a bedroom for every kid. That's pretty luxury on the whole.
In most dense cities, you just go to the playground with other kids. There's not shady people there at 10am on a Saturday/weekday afternoon.
You're projecting from a short list of American cities. Until Covid, I'd regularly see elementary school-aged kids riding the New York subway unaccompanied. They were better adjusted than the Bay Area's helicoptered teenagers.
