It depends on the restrictions and their motives. You are talking from the assumption that because you can find some good in a set of rules, that all the rules are making sense or that some rules maybe have a desired outcome, therefore the rule is inherently good.
As other people point out, there are other Christian and non-Christians that RECOMMEND the same set of rules, they do not REQUIRE the rules.
For example, smoking weed or talking to people that do “bad” things, has a strict rule in the JW org because they do not want you socializing with people at large and bring bad advertisement to the organization, not because they care for your health or safety, because that is belied by other rules (blood, field circus etc). If you can’t smoke because it may kill you but you can’t also save your life in an acute situation, those rules contradict each other logically and morally.
