Stuff hurting people is a public health issue, and the degree to which you limit its access is determined by its opportunity cost and its utility in the general public if access was less restricted.

Examples:

Motor vehicles kill. Their usefulness in society is huge. They're not banned. Levels of control and their fatality are deemed acceptable in for the most part.
Same with knives.

COVID kills. Controlling COVID by keeping people at home was useful for the most lethal strains and before we knew how to deal with it. Now that most governments have accepted that COVID can't be eradicated, the population has greater immunity and health facilities can somewhat keep up, the general public has come to accept that the opportunity cost of staying at home is no longer worth it. They'd rather earn money, go travelling, and accept the higher death rate COVID brings to the more vulnerable cohorts and accept whatever strain on the public health system this entails.

Guns increase the ease of mass killings. Their utility of being accessible by the general public is ...I dunno, you tell me. Different countries have decided on different balancing points, and decided on whether the deaths associated (not caused) with easier access to firearms is worth its utility - whether that's freedom, hunting, whatever.

Alcohol kills. There was once a prohibition. People decided it was too much fun to drink and have easily accepted that any alcohol related death is more acceptable than a complete ban on it.

It's just all a balancing thing. What balance keeps people happy and alive enough to pay taxes to keep the world going.

I was particularly fond of the gradual cafe downsizing such that only Mika and Chisato were left. It was always portrayed as being a big happy family, but I liked seeing the core family interact on their own. I remember the scene where Chisato saw Shinji in the bar and decided "Yep, it's a date. It's rude to intervene any further. Let's give them space" because it's Mika.
