Okay. Let me apologize. I think there was a major misunderstanding about this particular branch of the conversation. Right now you are really focusing on one tiny thing that I said. Meanwhile the overall point is being missed.
Yes, there should be only one use for a cantrip scroll. That use is to allow a mage who does not know that can trip to be able to cast it. That is the only use for such a scroll. The point I was trying to make, is that in the game right now characters who are not mages have yet another item that they can use to make mages obsolete and not needed.
In other words, if my fighter can simply pick up an item and even cast a can trip, then what good is a mage at all? My fighter cannot only take a lot of damage, deal a lot of melee and ranged damage, but he can also use scrolls to cast firebolt or frostbite or whatever the cantrip is. He can also use scrolls to make clerics null and void. So my fighter can cast revive cure wounds, guiding Bolt, etc.
So, again I say, why not just create a fighter, select a background that gives you sleight of hand and stealth, and then rely on potions, scrolls that heal, and so on and so forth? After all, now my fighter can do everything all by himself. He essentially has spell slots in the form of scrolls and potions and other magic items. So he doesn't need any other class at all.
That is my point.
For one "tiny thing", you do seem to want to put a lot of emphasis on it, which is why I focused on it. In your rush to defend yourself, you've overlooked the fact that in so far as spell casting/scrolls go, we've been largely in agreement. Other parts of the post I initially quoted were addressed in earlier posts, but this theme keeps coming back, so yes, I did focus on it, because despite largely agreeing with what's been said, I'm being told that I'm wrong. If I'm wrong, then so are the people I'm agreeing with, right?
In your fighter scenario, for example, I brought up UMD, which someone pointed out was a rogue thing in 5e. I thought that was dumb, since if it's going to be focused on one class, it should be bard. I didn't see any reason to elaborate on that further, and went on to respond to your "cantrip scrolls serve no purpose other than (insert your fighter scenario here)". My response to that was countered with "no one needs to scribe cantrips", which I never said. Now even you are agreeing that yes, there is a valid use for them. It would seem that I was correct in my assertion, which was simply a response to "there's no other use for them" that you postulated.
So yes, in the absence of UMD, or a background that allows casting of arcane spells/use of arcane scrolls, spell casting, from scrolls or otherwise, should be limited to casters that can actually cast the spells.
I've already said that wizards shouldn't be able to scribe Divine spells
