I can use my laptop without having any cloud identity tied to it - I don't need to give anyone my email address or card number just to log in. I don't have to upload my contact list or communication history to the cloud. I can install software on it that Microsoft or Apple haven't approved, and if I pay for software Microsoft or Apple don't take a cut. I can install different operating system, if I want. I can develop software on my laptop without special license and without paying Apple or Microsoft. When I develop software, I can share it with other people with laptops and they can run it. I can access filesystem in any way I want and directly modify, share or create files without them being transferred to the cloud.
Modern smartphones are very not like laptops.
Android is perhaps more like actual computer, but I'd guess that's mostly legacy - if Google made Android now, I'm sure they would make it more closed, and they are making it more closed with every release.

Second, OK, we ditch IP and flip to OSI protocols. Now apart from decreased security due to all this new software that'd have to be made, how would that make things more secure, at all? Everyone will still want to use the Internet, so it's not airgapping.
This argument makes no sense.
2) However, while I wasn't making an argument per se, more just thinking out loud about architecture choices, especially when they "mimic" systems that are not for the same purpose, I do believe that is a small part of the problem when it comes to mobile security as pertains to phones. And, maybe I'm also thinking that with that in mind, there might be room for a whole separate set of protocols and methods for interacting with the Internet (or a reasonable facsimile of it) from your phone, which is not a PC :-)

I'm still getting my feet wet with this critical thinking exercise, especially where an exchange of ideas is required to hone my own! I'll have to come back to this one...
Why make your peace with it, fight it!
Security through obscurity is not entirely worthless, but certainly not worth the cost of starting all over from square one.
For such a ubiquitous device that holds so much personal data and is portable in ways laptops will never be, one wonders why we are designing mobiles to be just like tiny laptops with all the same protocols, applications and OS APIs. First, sure, it's easy, but who ever heard of an old-school phone dying from a DDoS attack (which now is the current major mobile threat)? Or, being taken over by malware and every contact, password and account login sent to the Maldives for quick smash-and-grab sessions against bank accounts and so forth?
Maybe the intrinsic issue is really that we are still doing the "make it smaller" thing with tech and calling that innovation instead of "make it different" which out of the box often comes with intrinsic security of its own for actually being different.
