I'm not completely convinced by your argument. Maybe it is a way of marking reality but there's plenty of other phrases you could use instead of those. And how does "like" add anything at all to a sentence, when most of the time it's used completely ungrammatically? Saying something is like something else denotes non-reality if anything, because it's not the real thing, it's only 'like' it.
For that matter, how much of our regular speech these days consists of all those stupid trendy phrases?
