Three of the four items you list work because the government will use force against those who break the rule which prevents rampant abuse. If you want a government run and legally protected safe space then sure. I suspect most people talking about them don't actually want that.

As noted above, fatalism is an uninspiring argument here. "This won't work because you can't use force against those who break the rules" is framing-by-assumption that success is either all or nothing. Success is not all-or-nothing when it comes to creating safe spaces. If you take steps and someone works very hard to break through your steps, they will probably succeed. That does not implicitly guarantee failure, especially if success is defined as "safety improved" rather than "safety guaranteed".

The illusion of safety is dangerous because it makes people act in ways that ultimately make them even less safe once the illusion is broken. The current issues with social media posts coming back to bite people after years is a perfect example. It works until it doesn't and then you're in the deep end of the pool realizing you don't know how to swim.
