I don't think Apple should sell other stores within the App Store. However, I should be able to install unapproved apps/stores some other way.

The issue is that "their store" is the only way to install things on your phone. You're trying to set up a catch 22 where the only way to install a competing store is from an existing store, theirs is the only existing store and competing stores aren't allowed in it.

It is anti-competitive to prevent competing stores. How you do it is irrelevant.

>It's preventing other stores in their stor

and their OS. I don't care if they allow whatever on their store. I would like the option to go to other stores or even sideload my own apps without the store intervention. That's right now impossible without a) hacking the device or b) being a dev working on an app.
