You were comparing being scammed, and kept going back to "you can ask all these questions about for example being scammed. Yet nobody has a problem with an article how to avoid being scammed."
So do you accept that comparing the two crimes is rather irrelevant, as they are treated completely differently due to the issue of consent?
Additionally, you don't get scammed by someone physically overpowering you. It's usually done at a distance. That's why advice on it is supposed to work - because you can look for logical flaws, phone specific numbers if you suspect you're at risk, etc. That advice will not stop you being raped. That advice does not stop you going for a drink with a friend.
Do you agree that many times a rape could have been prevented by the victim?
No - because something would have had to be different, and you're not saying what. If the victim carried a gun, perhaps. If the victim happened to pick a different turn off, perhaps. If the victim's mum happened to come and surprise her, perhaps. If the victim managed to poke their thumb 2cms to the left and actually make contact with an eyeball, perhaps (although possibly put them in more danger). Bringing in 'sliding doors' alternative realities doesn't exactly help. Unless you are saying 'a 3in longer skirt/ trainers/not smiling/ would have reduced the risk to the point that it didn't happen' which is bizarre. You're asking people for hindsight.
But as a statement of fact, do you agree that many times there is a foreseeable risk of potential rape/sexual assault, and hence by definition steps could have been taken to prevent it?
You're confusing overall risk at group level with a binary 'an event did or did not occur' for an individual. Risk can increase or decrease but we will never know in advance which steps for each individual reduce the risk below the threshold of not happening unless you get to 'do not go out or let anyone into your home'. (Obviously 'do not come into contact with a rapist' would suffice but people tend not to tell you in advance that they are rapey).
There is so much guesswork involved in trying to assess which actions are safe and none of it is guaranteed. Do I ignore the creepy guy trying to talk to me on the train, or is it safer to smile and not get his back up? Is that inviting unwanted attention? Is it better to ask this other group of people for help, or will that turn their attentions on me and invite opportunists playing white knight?
If yes, why is it offensive to teach women about such hypothetical scenarios and potential risks?
I haven't said it is, btw.
