Ignoring the EU/USB-C thing, I gotta say a portless phone is a far worse idea.
If you have no choice but to charge wirelessly, it's now impossible to charge your phone while you hold it and use it, unless you get some kind of case that has a wireless charger built in and provides a cable connection - at which point you're back where you started, with a thicker device.
Also, wireless charging is actually hugely inefficient. You can use up to twice the power of wired charging just for the conversion to and from high frequency AC for the wireless coils. This also generates extra heat, which we all know is the enemy of lithium ion batteries. So you'll use more electricity and shorten the service life of your battery if you must always charge wirelessly.
And finally, Bluetooth still leaves a lot to be desired. If you strictly use AirPods then maybe it's OK, but try using any other device and you'll have to worry about "does this device support the highest quality protocols/does it support low latency/how easy is it to pair/etc". Some devices let you pair with NFC, but even that's not supported on most devices. Of course, this would be another way to get you locked into the Apple ecosystem (AirPods are naturally going to work the best with iOS devices).
Finally, did the EU actually specify that wireless charging devices must adhere to a standard? What's to stop Apple from just switching to a portless phone and redesigning the charging system to be proprietary - i.e. so that Qi chargers won't work, or will only charge the phone at extremely slow speeds?
Naturally Apple wants to maximize profits, but it always seems big companies start to ignore customer experience, or they simply depend on the fanboys who will buy whatever the company offers no matter how consumer-hostile it is. I don't think the EU was necessarily the right venue to force this upon Apple, but I can't think of any technical reason why Lightning is superior today than USB-C. At the time Lightning came out it was actually superior, but nowadays it's just a way for them to make royalties on the chargers they no longer include with the devices.
(And actually, iOS has had USB host support since the early days - the 30-pin to USB "Camera Connector" plug adapter was basically just a straight through connection. You could use MIDI keyboards and regular keyboards for example. A similar adapter exists for Lightning. And Apple even added USB flash drive support to Files--and by extension anything that utilizes their new storage APIs--a few years back. So the USB support has always been there to begin with. But until now they could charge you for a $29 dongle to access it.)
