I'm really interesting in the idea that safeguarding, and consent culture, are not enough. I am very much in agreement with that and it is something I've thought about a lot.
The reality is that human beings all have various dark impulses, and some more so than others. And some percentage will give in to them at some point. Maybe because they are morally bankrupt; maybe ignorant; maybe weak.
One tool to deal with this is the law, another may be procedural things like safeguarding practices.
But those are limited, and in some cases there are trade-offs. The "safest" possible set of procedures might mean that there is no way for valuable things to go on, so we find a level that seems possible to reach.
Other things are social pressures, teaching normative behaviors, and so on. And we do try and teach, for example, that violence is wrong, sexual violence is wrong, it's pretty widely accepted.
Where we fail though, IMO, is to realize that a lot of what protects us from bad behaviour in society is about developing the whole person. If we want people that don't develop weird sexual fantasies, maybe we shouldn't teach them that sexual fantasies are harmless, no matter what they are about.
If we want people to have self-control and the ability to delay gratification, or go without, maybe they need to learn that across a range of things - consumer culture, snacking, the idea that going without sexual satisfaction is crazy and maybe even weird and unhealthy, video games and social media, working hard for results in school or music or sports seems to be less and less of a thing. Our whole culture is creating young people who will struggle to have boundaries, to be sexually continent, to work hard for delayed gratification, much less to suffer for moral principles.
Such people might know very well that they should not do certain things, but when they are tempted, they are going to be poorly equipped to resist. Not to mention the ones who have internalized the message that they should not be expected to resist something they really yearn for.
Have all the laws and procedures you want, a society of people like that will not be constrained by them.
