Allowing competition doesn't mean you need to use that competition. Don't install any other stores and don't toggle the flag to allow alternate stores, and you would have and iPhone exactly as it is now.
There's no reason to expect it will be exactly like a PC, which is coming from a completely open past to a future which allows more locking down. The iPhone is locked down now, it's a bit ridiculous to assume they would immediately go straight to allowing anything and everything to be installed without any hoops jumped through.
Even Android requires you to allow unsafe sources to isntall third party packages. Why would anyone expect the iPhone to go farther than this when they're fighting tooth and nail to not even do this much?
