> This is unpopular every time I say it
Speaking for me, but this might be because while your points are valid:
> Every single aspect of the experience is worse
this is wrong (I can tell you that when my SO falls asleep hugging me in the bed, the mobile is a far better experience than a laptop to browse the web for instance - the tiny screen is a feature in this case), and it seems you are missing the elephants in the room that explain why people are using mobile despite those issues, and you are not addressing the use cases.
This makes your comment read like you are disconnected from reality. You might not be wrong, and it might just be a matter of changing the perspective a bit. In the new perspective, you would show that you understand why people actually browse the web on mobile and address the issues from there.
"You should not browse the web from a mobile" doesn't help at all. Most people do it, and although it's imperfect, people seem to go on on their lives anyway.
You probably need to motivate your view a bit more (so we can go from "is it indeed the case that we should stop browsing the web from a mobile?" to "this person is right, we should definitely stop doing this, what now?"), and address the specific use cases where people use the mobile and provide alternatives.
Alternatives like "just don't browse at the bus stop, allow your mind to be bored / to relax a bit" are perfectly valid. One can disagree with the proposal, but that's one solution.
