Well, I'm afraid you kinda missed my larger point due to a nitpick into an example. Please replace it with something else appropriate (physical keyboard? USB-C or microUSB port? whatever really) and argue about that :/
How about we just don't argue at all, because you're clearly misinformed if you think iTunes is the only way to get music on iOS. Or pretty much any of your other assertions.
Then you should have mention that and not use your weak arguments to try to prove your point.
I have an iPhone and I don't use HomeKit, AppleTV, CarPlay or the iTunes Store, and use Whatsapp instead of iMessage.
And I'm afraid I can't see how replacing the headphone jack with a physical keyboard would make your argument better. If you want to charge your phone using microUSB there are hundreds of options.
