What's wrong with clicking on an unknown link? It can only hurt you by taking advantage of an unpatched security bug in your software. But if you have that, you might be vulnerable doing all sorts of other things on the internet. And you probably do have that and are vulnerable doing all sorts of other things. It's just not very likely to hurt you in either case.

It's about preemptively scaring people on how much is easy to have them do this and that action when the communication looks legit

And following a link from a scam email has a greater risk of drive by infection, since it is specifically crafted for that and has the user already has convinced being legit: you have to take in account that once the seems legit feeling is active escalating action gradually is likely to succeed.

It's about context and psychology. If one of those link from an officially sounding page had a download this to check if you have been scammed a lot of people would have done just that. In the same way you need to preemptively scare them, so that the message of trust no one really comes across vivid
