Here's what a rational, profitable scenario would look like to me: in the not-too-distant-future, you land in country X and you get prompted if you would you like a local number by partner Mobile network. If you agree, Apple submits your electronic ID[1] to the Mobile Network for KYC purposes (with your opt-in), you pay with your Apple wallet, and you get a local number. The network gets paid, and Apple gets its cut (as well as a subsequent payments, if it's a PAYG plan) - and you haven't even picked up your baggage from the carousel. Apple can even play off networks against each other and pick the more profitable ones, and consumers get a sleek onboarding experience for a fee, or bundled with your Apple TV/iTunes/iServices subscription, so you can resume watching season 10 of Foundation while you wait for your Uber.

Removing the SIM slot isn’t a step into that direction, removing standards compliant eSIM support would be.
Or maybe your comment isn’t meant as a criticism at all, I think that actually sounds pretty awesome. As long as we retain the ability to load our own eSIMs.
Please tell me you are serious about this. Tried looking into this earlier and found out that eSIM is extra proprietary, which means no hobby devices, like those 3G/4G/GSM connectivity Arduino modules.
